Do not let the good reviews fool you.

Rating: 3/10 (20 June 2012)

I know this is only entertainment, but in order to entertain there are certain goals that must be achieved. This movie deserved believable characters, believable situations, a top-level science fiction script and the best special effects of all time; unfortunately it has none.
If your idea of entertainment is that anything is possible because "it is just a movie", then you have a chance of enjoying this film. Otherwise, you will be seriously bothered by completely flat, silly, unbelievable characters; silly situations created because the characters are plain dumb; a script that offers a number of plot holes, very few suspenseful and uninteresting moments, scientific background that requires no degree in science to notice that are just foolish; and special effects that are as good as any other recent movie but by no means a reason to watch this one.
I went to watch this movie with low expectations because of the reviews, but it was much worse than expected. I have never been so disappointed of a movie in a long time.
