Actually when I first heard about the movie I was not interested, not my kind of movie. When I realized I could see it at the IMAX in 3D, I thought what the heck I'll give it a whirl.....and WOW what a great movie. My hands broke out in a sweat several times and the 2 hrs 40 mins seemed like 30 mins. I really hope there will be a sequel so I can experience it further. Thanks James Cameron for a great production.
