This movie isn't as good as the first one, but it is entertaining. No need to watch it in IMAX unless an IMAX 3D version is what you're watching. I went to see it in IMAX and it was just bigger, so if you're vision is just fine in the regular theatres, watch it there, save the money. Scarlett Johansen was fantastic. She didn't have ALOT of parts, but it was good. I thought that anyone could've played the role of the bad guy. No character development, though you knew most of the characters from Iron Man anyway. I love Don C. but he didn't need to be in this one either, looks like they put him in for his name, may have been a better feel if they kept the first Rhody. All in all, it was an entertaining movie. Good special effects and a halfway descent plot. I give it 4 stars.
