Overall, the movie was great. The action scenes were exciting and the story line was good.
There were a few scenes that were a little iffy as far as the CGI (special effects). This wasn't enough to ruin the movie though.
I would go so far as to say I'd watch it a second time in theaters. I will most likely own this. It by no means is as good as Iron Man (2008), but that's to be expected. :)
