Saw the movie this weekend and loved it. The action was good as others have pointed out, but what really hit me were the little touches that connected it back to the old TV show. From the opening scene with Banner in the weird chair thing in the lab and the bullseye on his forehead, to the security guard Banner had to bypass with the pizza, and especially the touch of piano music when Bruce was down and out in Mexico... all those things really hit me the hardest. And was it me, or did Betty offer him stretchy PURPLE pants which he turned down?! I wasn't sure on the color.
Overall, it was very well done (better than the Ang Lee version) while not quite up to Iron Man's level. I definitely loved the last bit with Stark showing up. Cannot wait for the Thor movie and the Captain America/Avengers movies! Ant/Giant Man I could do without though. If Cap was really in there somewhere, my bet would be somewhere in the hospital when the general was visiting the soldier guy. Might have to see that part again to check...
