Okay, I'll expand for the sake of discussion.
GotG2 was slightly lame, imo. "Brandy" by Looking Glass and "The Chain" by Fleetwood Mac while was purposeful for some of the scenes played too often. What made the soundtrack work for the first film is there was no repeat of the songs. "Brandy" was Ego's backstory and I didn't like that element.
IronMan 2 and 3 were weak story wise. Especially 3 with Pepper wanting him to destroy the suits which he did do, I can't even rewatch either of those films.
I couldn't get into Capt America: Winter Soldier. I don't see the appeal of Bucky, and wasn't vested in his plight enough to care.
I'm trying to pick the films that didn't interest me or felt bleh about. I am certain I've got a couple of others but for the most part I do enjoy Marvel Studios handling of their characters.
Here's an idea, lets Magic Mike Gambit and the movie will get done. LMAO - I kid of course.
