During the '90s heyday of Marvel animation, a number of characters were given animated series, though few were anywhere near as successful as X-Men or Spider-Man. Plenty of these shows ended after a single season, mostly because they were lousy. Among them, however, is Silver Surfer.
Silver Surfer is an inherently weird character, a "cosmic sentinel" whose stories are often rife with themes of existentialism and philosophical struggle. Rather than tone it down for the show and turn it into a simple beat-'em-up heroes and villains show, the animators leaned into it. Episodes addressed imperialism, slavery, and nihilism (specifically explored through series villain Thanos). It also incorporated some of the strangest characters the cosmic side of the Marvel universe has to offer, including Adam Warlock, Pip, Uatu, and Eternity. The show also used some imperfect but nonetheless charming CGI to bring to life the Surfer's interstellar environment. The result looks like it's ripped straight from a Jack Kirby Silver Surfer comic book page.
Unfortunately, a legal dispute between Marvel and Saban led to the show's cancellation after a single season. It's a huge bummer because this was one of the more interesting, albeit strange, Marvel shows of all time.
