I was referring to the house style Marvel Studios has. The films themselves are diverse, yes. For me however, I find myself only watching a select few of them from time to time.Funny, what MCU movie I feel like watching really depends on my mood, since I find them so diverse in style. I guess that's because it's a matter of opinion, not fact.....
Captain America TWS: For my James Bond/Mission Impossible thriller.
Iron Man 1: For my scifi hero's journey.
Thor TDW: For my swords and sorcery fix.
I haven't watched an Avengers' movie all the way through in years. Just the various action scenes from time to time.
GOTG for my space scifi, when I don't feel like rewatching Trek or Star Wars.
Things like IM 2-3, Ant-Man, Thor 1, Incredible Hulk, The First Avenger collect dust on my shelf. When Dr Strange comes out, I think I'd rewatch that one a lot for the visuals.
