I thought the movie was thrilling. Sure the physics of running under water and suits being able to take the pressure of 6 miles below see level isn't the most accurate, but it is a movie. Kristen Stewart also doesn't need to be running around in lingerie whenever she takes her suit off, however, she sets the tone of the movie very nicely, her acting is quite good considering that the plot finds the actress under constant duress for 95 minutes. I don't understand the critics that say it is "boring". This movie is the furtherest thing from boring if you have any capacity for imagination. If you like suspense and a little monster sci fi this is definitely worth a watch.
