So I did watch it earlier today and I thought it was better than expected lol. It definitely felt like a Marvel film, so I wasn't as into it as I would be DC. There was a part where Banner was referencing Loki, and he said, "He really grows on you, doesn't he?" I'll admit that he kind of did. At first I was like.. why is this space elf using his blue wand to try and steal a sith datacron? XD But his character was kind of cool.
I didn't care for Thor or Captain America - Ironman was easily the best character with his wit. My favorite parts were always where Hulk was fighting lol. So yeah, not bad - I might watch the second one out of curiosity.
