Double posting to bump this up. Just watched this movie today and I advise everyone to stay away.
The story and acting is extremely cheesy, the situations are ridiculous and the decisions are stupid. That is something I was prepared for though. I didn't expect to be intellectually stimulated here; I just wanted to see more of what I saw in the trailer, on the big screen.
The problem is that there is about 20 minutes of that in the whole two and a half hour movie. I don't know where the hell all the money went because there are movies that cost half as much and provide twice as much mindless entertainment. This movie is not about the disaster, it's about characters you could care less about, going through the disaster.
If you don't enjoy watching people mope, look worried, and display just how kind and caring they are via horribly cheesy acting, then walk into the theater about 35 mins late, leave in 10 mins and come back for another short portion in 15 more mins.
Better yet, rent the movie so you can skip directly to the fun parts. The several second long cutscenes of tsunamis sprinkled in between the "emotional" bits are literally as long as they are in the trailer.
I'd give this movie 3/10 for the two awesome (though dumb) sequences but they really aren't worth the admission price. If you never listened to online reviews, listen to this one, you will regret wasting the money. The movie was simply unbearable.
