Iron Man 2 was a lot of fun. Its biggest sin was not being better than the first movie; but how often are sequels really better than their predecessors?
Spider-man 2, The Dark Knight, Empire Strikes Back, The Wrath of Khan, Godfather II, Toy Story II, X-Men 2.
Usually it's the third movie where the wheels come off.
Sure those are good sequels but there are plenty where part II actually is of considerable lesser quality or "wheels coming off" and IM2 doesn't fit that bill. I'd call out Gremlins 2, Ghostbusters 2, Die Hard 2, Tomb Raider 2 or X-Files 2 for starters. The dissenters of that movie pile on too harshly. I mean crap if it were that bad WOM in our social media age would've killed it not to unlike what happened with Green Lantern. Iron Man 2 just isn't a bad film despite some people thinking it had to be a film like you listed above.
IM2 was entertaining and has ONE really bad scene, drunk Tony. Even that in context is understood, he thought he was going to die. His blood toxicity level was like 89%.
