The latter half of the film is one long feeding frenzy, guided by a familiar horror-film principle: survival of the best-looking.

Leviathan is intermittently interesting, but it's a bad sign that the movie starts losing its punch when the monster shows up.

A mostly confident, if familiar, slice of sci-fi / horror comfort.

The effects by Stan Winston are typically polished, even if the creature looks like the usual assemblage of teeth and tentacles.
