I did a marathon with Iron Man 2
I also did it with The Rocketeer, Iron Man 1,2,3 and titled it When Men Use Technology For Good. Check out my blog.

Iron Man 2 is not as good of a film as the first movie but it's definitely not as terrible as many critics and audiences made it out to be. However in the realm of the Marvel universe, it's def one of the worst movies made thus far as it lacked a true threat and felt too much like a build up to Avengers than an Iron Man sequel. Iron Man 3 is a better film in my personal opinion although that one has its flaws to. Overall this trilogy is pretty consistent but I think Iron Mann 2 could've been better.
