The setup is so contrived. Look, the special effects are just that, special in this movie. They are technically brilliant, but without a good script and characters that come alive, after a while I found the effects repetitious and boring. Technically brilliant certainly, but stuck in a lifeless movie. Other than the technically impressive special effects, I liked seeing Hunt and Paxton.
Hunt is so smart, tough, and sensual all at once.
Paxton is a great minor actor I have enjoyed for a long time. As much as I was glad to see them again, I never found their characters in the movie believable. Finally, kudos for the nice computer graphics. Realistic without being overdone. It is rated PG-13.
