Well, let's see - I don't really watch a lot of movies, nor am I into comic books that much - here is an outsider's view:
Man of Steel - some Superman movie...Last one I watched was Superman 2. Yeah. I'm not that much into him and this, from what I know, is a reboot - I'm not much into reboots either. It never was on my radar (I thought it was actually out already), so no.
Thor: The Dark World - well, I watched Avengers and know very little of Thor himself. I'll happily skip this.
Iron Man 3 - I watched the first one and it was alright but I was never invested enough to watch the second one.
Kick-Ass 2 - Never watched the first but I intend to...at some point. After that, I'll see about 2.
Sin City 2: A Dame to Kill For - It's probably the highest aticipated one for me. Erm, and I heard of it now. I really liked Sin City, I'd want to see what would happen in a sequel
The 300 Sequel (yeah, that's a thing) - nah, I already feel robbed for watching the first one.
The Wolverine - wasn't there a movie about him already? I believe it was called something else but I seem to recall it being a thing. At any rate, I was never really a big fan of Wolverine. I know, grab your torches and pitchforks but I don't find him bad, just not as interesting. For what it's worth, I might give it a try.
R.I.P.D - I've got no clue what that even is.
