Critics Consensus

If Sea Fever never quite heats up as much as it could, it remains an engrossing, well-acted sci-fi thriller with effective horror elements.

Kermode & Mayo's Film Review

It's made well, made intelligently, and it uses a very small budget with confidence...I was really surprised by how much I liked it.

Tribune News Service

An absorbing (if sometimes muted) wrestle with the notions of ethics and infection, in a moment that couldn't be more appropriate.

Rated: 2.5/4

Sea Fever may not appeal to those seeking escapist entertainment, but the bleak ecological message will attract those who remember such dark warnings as the Doomwatch tv series and film....

Rated: 3/5

Britany Murphy

The Reel Roundup

A film that warns about the ecological impact of humankind, as well as how little we truly know about the ocean and what lies in its depths, Sea Fever is a sci-fi thriller that's about more than just what lies on the surface.

Nashville Scene

As enjoyable as the 1989 Leviathan, but very much rooted in The Now.

My mind was wandering a long way before the finish. Nothing new or interesting and the acting was hit and miss. A mediocre B movie.

Rated 1.5 out of 5 stars

Poor, I'm afraid. It sounded so good from the publicity, but the "creature" is unexciting and the plot crawls along without any real sense of tension.

Intelligently written, well acted, and expertly directed. Effective science fiction with hints of cosmic horror. A thought-provoking slow burn that won’t appeal to the Saw/Chucky/Jason crowd. Sea Fever is a film in the tradition of The Thing and Alien, but more sedate version with human relationships and interaction more front and center.

Rated 4 out of 5 stars

Awful story. Predictable but totally ridiculous. Not worth watching. Casting only surpassed in wierdness by the accents.

Loved this movie. The characters and performances were legit and this thought of being stuck on a boat with a parasite in the water is terrifying. Tim Treakle

This movie was stupid from start to (especially) finish. A complete waste of time.
