Just got back from seeing it, not in IMAX which was sold out but in just 3D. The 2.5 hours flew by and every Avenger gets a chance to shine. Was most impressed w/Mark Ruffalo. This movie finally IMHO captures the complex nature of Banner/Hulk and not just a Jekyll & Hyde show. The CGI never seemed OTP at all. Oh, and a lot of the LOL humor involves the Hulk.
