The physicists are probably scratching their heads about the movie's time paradoxes. Other than that, it had good acting, story and scenery. I plan on seeing it in IMAX when it arrives in the theaters.\r\rJim Wolford\rIndianapolis, IN

Enjoyed the acting. The ending was a surprise. FX were spectular!

Entertaining....If you want an entertaining break from reality with tons of action and crazy, wicked aliens... this is the movie for you:)

great story plot. it all tied together. i loved the kid with the knowledge about volcanos....and the guy that lightened up the whole movie, talkative but lovable. suspenseful
