Movie franchises with unnecessary sequels

This CGI version of Rock 'Em Sock 'Em Robots has spawned a mind-boggling five films of varying degrees of quality (though most remain on the lower end of the spectrum). While none of the movies are great, it makes sense the popular toy franchise might spawn a movie or two. But five (including the upcoming Last Knight in 2017)? Enough is enough. They ran out of interesting stories a few movies ago, which is made all the more obvious by the fact that explosion maestro Michael Bay decided to semi-reboot the franchise with a new human cast led by Mark Wahlberg in 2014. That effort was big on spectacle, but light on just about anything else (including good reviews).

Regardless, the Transformers movies have accounted for more than a billion dollars at the box office—so those sequels won't be slowing down anytime soon.

The brutal, low-budget horror film Saw was a surprise hit—so the studio capitalized quickly and made it a staple of Halloween season for the next several years on the back of six sequels. Turns out the gimmick of tricking people and locking them in death traps doesn't exactly stretch that far. The seventh (and allegedly final) installment, Saw: 3D, made more than $140 million at the box office despite the fact that the critical reception was pretty terrible—so after six years on the sideline, Saw is coming back next year with the semi-reboot Saw: Legacy.

It's hard to believe it's been 15 years since the first installment in the Fast and the Furious franchise roared into theaters. Though it's become a box-office juggernaut of insane car action, the middle years of the series weren't great—they left Vin Diesel on the bench for 2 Fast 2 Furious, focusing on Paul Walker instead (R.I.P.), then left out pretty much all of the main cast for the spinoff The Fast and the Furious: Tokyo Drift. Amazingly, those duds didn't kill the franchise—but they were enough to make the studio realize that Diesel, and the camaraderie of his character's gang, was what made this franchise run (no pun intended). They reunited the cast and returned to the formula of the first film for 2009's Fast and Furious, then quickly started ramping up the insanity for the three subsequent followups (and counting). It worked: each of the past three sequels have made more money than the prior film—and the franchise shows no signs of slowing down.

This franchise helped kick off the modern-day spoof genre in 2000, and at the time, it was a fun way to poke fun at horror tropes. But the horror genre has changed a lot in the decade since, and Scary Movie never managed to get any smarter. They stretched the spoofs out for four more films, mostly just doubling the fart jokes and less-than-clever jokes about other movies. Oh, and a boatload of cameos (some notable Scary Movie franchise alums: Charlie Sheen, Kevin Hart, Marlon Wayans, Ashley Tisdale, Anthony Anderson and Anna Farris). The last sequel, 2013's Scary Movie 5, was so bad even original star Anna Farris opted not to return. It was generally considered terrible (and didn't make much money, either). It seems to have been enough to finally but a nail in this spoof coffin. An average grade of 4 percent "Fresh" on review aggregator Rotten Tomatoes will do that.

The first A Nightmare on Elm Street film was a master class in horror, meshing the slasher genre with a psychological thriller that still terrifies teens and adults to this day. But after that the quality starts to wane. Nightmare on Elm Street, Part 2: Freddy's Revenge wasn't great, but the franchise rebounded with A Nightmare on Elm Street 3 – Dream Warriors. The next few sequels were pretty terrible, with the only real highlight being the ultra-meta Wes Craven's New Nightmare in 1994, which brought Freddy into the "real" world to remind us just how scary he could be. But that's about it. A 2010 reboot was a generic disaster, and the franchise has been on ice ever since, though it's worth noting original star Robert England does have a pretty cool idea for a new sequel that would imagine Freddy in different ways within the victims' subconscious. Hey, it couldn't be worse than Freddy's Dead: The Final Nightmare.

Considering the legacy The Exorcist has in horror circles, it's easy to forget William Friedkin's 1973 horror classic actually inspired four sequels (with two of those essentially the same messed up movie re-cut into entirely different films). Exorcist II: The Heretic tries to pick up after the first film, telling a story that nobody really cared to see. The movie wasn't just bad—it's considered one of the worst films ever made, and Friedkin himself slammed it as an "abomination." The Exorcist III, released in 1990 and set 15 years after the first film (and ignoring the events of The Heretic), wasn't much better. It was butchered in post-production and received generally bad reviews.

But the weirdest Exorcist sequels might be the last two. Exorcist: The Beginning and Dominion: Prequel to the Exorcist were essentially cut from the same film source (an early 2000s sequel starring Stellan Skarsgård, Izabella Scorupco and James D'Arcy), though they turned out to be drastically different movies. Long story short: The studio got cold feet shooting the film, and replaced Dominion producer Paul Schrader with Renny Harlin to completely re-cut the film. That ended with the release of the critically panned Exorcist: The Beginning, so the studio brought Harlin back to finish his vision of the film and released it too. Which is really strange for a Hollywood project. Dominion was better received, but the reviews still weren't great.

The first Scream was a monster hit for a lot of reasons. It was a return to form for horror legend Wes Craven, and turned the slasher genre on its head with a whodunnit story that was extremely fresh in 1996. Scream 2 was arguably better than the original, but they really should've stopped there. By the time Scream 3 rolled around in 2000, it had become the type of movie it used to skewer. It looked like Scream was dead at that point, but it came back to life with Scream 4 in 2011. This one wasn't as bad as Scream 3 (how could it be?), but the general consensus is that it was wholly unnecessary. Looking beyond the film franchise, Scream has since been adapted into an MTV series that's a decent mystery show… but not really true to the horror the franchise once represented.

He's one of the biggest heroes in comic book history, and a who's who of stars donned Batman's cowl in the '80s and '90s with wildly varying degrees of success. Tim Burton's 1989 Batman and 1992's Batman Returns were masterpieces, but then Burton and star Michael Keaton left the franchise, and the studio decided to go in a more commercial direction by bringing in Joel Schumacher for 1995's Batman Forever and 1997's Batman & Robin. Val Kilmer and George Clooney played the Dark Knight, respectively, and both films were pretty bad—the tone was campy in the worst ways and the casting was as '90s as it gets (see: Alicia Silverstone and Chris O'Donnell). They were so awful they creatively killed the Batman franchise as dead as Bruce Wayne's parents, and it stayed that way for years. Thankfully, Christopher Nolan got things back on track with 2005's Batman Begins, a full-fledged reboot complete with origin story, but even some hardcore fans believe his trilogy was getting a bit tired by the time 2012's The Dark Knight Rises rolled around. Ben Affleck's version of the character is due to get his own standalone feature in the next couple of years; time will tell where it falls on the franchise spectrum.

Dig deep and you might remember Tremors, a quirky little 1990 sci-fi flick about the residents of a small town (including Kevin Bacon and Family Ties dad Michael Gross) under siege from crazy sandworm-esque creatures. Based on that description, would you have ever imagined it would spawn five sequels (plus a TV series, with another film in the works)? The premise worked in the self-contained world of the first film, but the four films since have tried to build a full-fledged film universe (the fourth installment was actually a prequel telling the creatures' origin story). Michael Gross, a.k.a. Burt Gummer, has been a recurring presence across pretty much every iteration, but none of the sequels or spinoffs have come close to matching the wacky fun of the original.
