Query: SOOOOOOO LAME!!!

SO DUMB, yes I get it's a comic book movie, and I get the fantasy aspect of it, the problem is the acting, it is among the most contrived and forced performances I have ever seen. So bad, so so bad. Thor is horrible, Captain America even worse, Iron Man acceptable, only character worth a crap is Mark Ruffalo's Hulk, and he even struggles, some of these guys are great actor, yet they seem like they are cringing at their own words, as if they can not believe they are being forced to say this awful dialogue. Action and FX are great of course, but at two and half hours it is torture to sit through the other crap.
