Decent but not as good as the original Although the movie which this is based on is as old as I am I can still say that this movie is not as good as the one from 1972.
Sure, the cast is talented, the effects are impressive and the pacing is well done. The entire movie is, in fact, well done. It's just not inspired. Or inspiring for that matter.
The script is quite basic, although in the movies defense, it doesn't have to be especially complicated as the environment should be the key element here. There are still certain parts that needs to be sharp, the dialogue for instance. And the characters.
Again, it's well done but nothing that you remember years after you saw the movie. And with a movie like this you really should remember quite a bit.
One thing I have to give the move makers is the fact that people die, even the ones you didn't expect to die. Then again, the ones you expect to die, dies as well (and at times exactly the way you thought they would).
The laws of physics are set aside when the script calls for it which really is a shame. I can think of a number of settings in an Atlantic cruiser turned up-side-down without making stuff up.
If the movie had been just a disaster flick without all the touchy feely interaction between the characters, as they are to uninteresting to make that part work, I think it'd been a better film. Or the other way around; a lot more interesting characters and emotions and less focus on the environment.
As of now, it ends up in between these chairs and the end result is a rather bland movie that didn't impress very often.
