This is quite entertaining fair.
If you have a couple of hours to kill why don't you just go for it and watch the movie?
If of course you do , please don't expect anything original, don't get me wrong it has its tense moments and at times is very definitely claustrophobic, even I found myself thinking "what was that " as I caught a glimpse out of corner of my eye.
This movie is basically ALIEN underwater, down to the female hero running around in her Ripley knickers in and out of space suits paying 'homage' to Ripley's original. Believe it or not, there is even one scene where the hero gets swallowed by a creature and she bursts out of ITS CHEST.
With that in mind you can not obviously take this film seriously which is probably why it was a big fat bomb in the cinema.
You have of course the usual stereotypical characters, it seems quite obvious that you know the ones who were going to die and who provides the cocky light entertainment, but they are characters that don't last long.
I said at the beginning of this post that you could give this film a try, it's not bad , not great
but if there's nothing else to watch on a Saturday night give it a go.
