YMMV / Voyage to the Bottom of the Sea

• Hilarious in Hindsight: "The Cyborg" sees Victor Buono as the Big Bad taking on aquatic heroes. It wouldn't be the last time either.
• Magnificent Bastard: "No Way Out": Victor Vail is an Eastern Bloc assassin who is introduced succeeding at a training mission in a replica of the Seaview and then has a friendly chat with his handler while dismissing the revelation that he killed one of the instructors by hitting him too hard. He kills and impersonates an official who will be on the Seaview at the same time as Anton, a wounded defector, by posing as a chauffeur and booby trapping a car seat. Victor's attempts to be alone with Anton and kill him are constantly interrupted, and he maintains his cover as an impatient but ultimately reasonable official. He attracts little suspicion until he has to take a call from his cover identity's superior. He tries to bluff his way through the conversation, and when that fails, kills or incapacitates many sailors while fleeing through the ship. He makes it to Anton's room through an air vent and learns that there is another deep cover agent aboard who he didn't know about. He is amused rather than slighted and doesn't protest when the other agent lets him get captured to sell a Wounded Gazelle Gambit after they fail to kill Anton together.
• Seasonal Rot: The television series began with largely the same tone as the 1961 film, but by the fourth season they'd gone quite loopy and neck-deep into fantasy elements. Whether that's a good or bad thing is up for debate, but it's hard to believe that the show moved from "City Beneath the Sea" to something like "The Deadly Dolls" (the latter is exactly what it sounds like: a story about cursed puppets that would seem more at home in The Twilight Zone (1959) than in what began as "serious" Sci-Fi).
• Special Effects Failure: The giant squid in the film. Also, the shark is clearly a plastic toy, though it's handwaved as the shark having been drugged for medical reasons.
• Spiritual Successor: SeaQuest DSV.
• Took the Bad Film Seriously: Richard Basehart, full stop, period.
