I saw F7 yesterday as well, took my son, it was a enjoyable flick. Very cool stunts, action and effects.
Thor, Guardians isn't really in the avengers series. You need to see the first Avengers movie, if you haven't already seen it.
Watched the Winter Soldier last night, I really enjoyed it alot. I actually think it was one of the better Marvel movies, who the hell were those guys at the end though!? The ones that had scarlet witch and quicksilver in the cells?
