Despite the technical wizadry and rich production value on show, its all so incredibly stupid and predictable, with most of the characters flaccid and uninvolving. The necessary hold-your-breath underwater sequences are in here too, and they are indeed tense, but then moments like those always are in the movies. That said, I did enjoy 'Poseidon', it delivers what you expect from fluff like this. It isn't trying to be anything other than low-brow button pushing, and for the most part, it presses the right ones with precision.
