I don't care about the MCU beyond IW at the moment because so far, actors and characters just don't wow me. Before the MCU started, I was always a Hulk fan, I didn't check out Iron Man for the longest time but RDJ just had something about him that was magnetic and I was hooked on wherever else this went, and Evans turned me into a fan of Cap when I knew nothing about the character before movies and might care less with a different actor. Hemsworth is ok but I actually enjoy Loki most in Thor movies to be honest.
Guardians was entertaining and I'll check out the sequel for sure but no one really stood out in there worth wanting to follow them for a whole epic storyline, where at this point, I'm very invested in the lives of Cap, Iron Man and Hulk in the MCU and I keep wanting to see the next stage in their evolution. Ant-Man was entertaining but I could care less what happens to him and nothing is exciting me about the other future films in MCU, I honestly think I'll be done once the characters I like most are out.
