I don't go to the movie theatres very often. A movie has to really grab my attention, AND look like an amazing 3-D experience for me to go. Otherwise I'll wait and watch it at home. I hadn't read the reviews, and am not a movie nerd by any means, but I'm almost always easily pleased by a film.
I loved the 3-D, and I loved the suspense. I just found the plot to be boring as hell. Someone said it was almost like they took the last 20 minutes of a movie and stretched it into a full length feature and I couldn't agree more. Someone else made a Super Mario reference, and that was the EXACT analogy I gave to my wife as we were walking out of the theater.
I wasn't upset I spent the money, nor was I upset I went to see the movie. It provided me the entertainment that I was expecting when I decided to see it, I just wasn't impressed with the movie itself. The visuals were stunning, the intensity was overwhelming at times, particularly at the end. I sat up in my seat and took deep breaths a few times during it. I LOVED that. The characters and plot could not suck me in on any level though. And if it wasn't supposed too, well, mission accomplished. I'm just sayin...
Overall though, what I wanted from it delivered. Enough that I'm considering seeing it again while I can in 3-D. And I haven't seen the same movie in a theater in over 20 years. Maybe I am a movie snob though. I got up and walked out in the middle of Jurassic Park and never did see the rest of it. I was 11 at the time.
