I thought it was slow in the first 30 minutes because I kept dosing off. After that it was pretty good lots of action great effects. However the ending was really not ending. There is more to the story so I'm thinking there might be another movie to finish the story. I watched it on a standard screen. I've heard that on the 3D screen some people got sick and I can see that. There is allot of action for 3D. Just make sure you don't sit next to someone who talks all through the movie and takes part of your seat and coughs. All in all it was a good movie.
