The Top-Rated Episodes Of The Curse Of Oak Island According To IMDb

For years, "The Curse of Oak Island" has mystified viewers with its in-depth exploration of the Oak Island mystery. Since 2014, the documentary TV show has followed brothers Marty and Rick Lagina and their team of investigators in their attempt to search for the legendary treasure that is rumored to be buried somewhere on Oak Island in Nova Scotia. Though the show's nine seasons have seen the team very gradually progress through several breakthroughs, such as excavating certain odd artifacts and uncovering enigmatic markings, the infamous treasure trove itself remains undiscovered. 

However, two particular episodes of the series stand out among the rest, as exciting milestones in the team's quest to explore the island and determine whether the legends are true. Both of these episodes also share a particular focus on one of the greatest mysteries from the show's earlier seasons — the secrets housed within the mysterious abandoned shaft known as "Borehole 10-X."

Fans rate 'The Big Reveal' and 'Voices from Below' as the best episodes

According to IMDb, fans of "The Curse of Oak Island" rate the final episode of Season 2, titled "The Big Reveal," and the 12th episode of Season 3, titled "Voices from Below," as the best episodes of the series. The episodes are tied with one another, both sitting at a rating of 8.6 out of 10.

"The Big Reveal" features a major moment relating to Borehole 10-X. Upon stopping a dive to the flooded bottom of the shaft for safety reasons, the team instead opt to use sonar equipment to map it out. In the climactic moment of the episode, the investigation team are surprised to discover that the scan indicated the existence of a chamber housing important artifacts deep below the surface. "Voices from Below" continues this plot thread, with the episode seeing the team bring in professional diver John Chatterton to locate the chamber. Chatterton's dive attempt proves successful, with the episode seeing him reach the mysterious submerged chamber, confirming its existence once and for all.

While viewers would later come to discover that the chamber was essentially a dead end in the Lagina brothers' investigation, the potential importance of this discovery in solving the island's secrets felt enormous at the time. There are still big questions for the show to answer in the future, but these two episodes of "The Curse of Oak Island" made the audience's imagination run wild when it came to one of the show's finest mystery boxes.
