Behemoth, the Sea Monster Ratings & Reviews
- MechaJayZilla15 October 2025It's an enjoyable monster flick. There's no denying the social commentary on the proliferation of nuclear weapons, a common theme among monster movies of its time (i.e. Godzilla, et al). However, it seems to have taken a lot of its story and style from The Beast from 20,000 Fathoms. The special effects - specifically the stop-motion animation - are brilliant at times, and then suddenly lackluster, which was unusual for animator Willis O'Brien, a master of the craft. Still, it's worth watching.
- Hedgehog204931 January 2026If you like the scene in monster movies where men stand around dryly discussing and explaining the creature, then this the film for you! Its hard to care about any of the characters, anyone with personal stakes in the action is quickly forgotten about. There is only one big monster rampage scene near the end and it's a good one. The director's later feature, Gorgo, remains the superior UK monster film.
