I've seen all of them in the cinema, including Star Wars in 1977. I've also seen all the prequels, as they are pretty big films of their time, but they left me baffled as to why people fawned over this particular brand. The only films we raved about as kiRAB were horrors and war films.
Yes ALL superhero movies, (there's probably plenty of obscure ones I haven't seen, but I'm talking about the main ones like Spiderman, Iron Man, Fantastic Four etc) - and I like Christian Bale as Batman the character, the film was average.
The only one I haven't seen at the flicks was The Happening, which was a good job otherwise I'd have been arrested for affray.
