Phase 1 worked really well as standalone films, Iron Man 2 notwithstanding. Like each one told their own stories with some subtle hints here and there. Phase 2 is when things started to feel like each film was in service to a greater cause (Infinity War). Weirdly, I enjoy the Phase 2 films more than Phase 1 in spite of that. And for Age of Ultron specifically, I guess I wasn't too bothered by all of the world-building stuff because I was already invested in the universe and I wanted to see what was coming next. But I can definitely understand how people are put off by it.
Phase Two includes Iron Man 3 (2013), Thor: The Dark World (2013), Captain America: The Winter Soldier (2014), Guardians of the Galaxy (2014), Avengers: Age of Ultron (2015), and Ant-Man (2015).
Iron Man 3 has nothing to do with IW?
Dark world - definitly leading up to it.
Winter Solider - nothing to do with IW
Guardians of the galaxy - definitly leading up to it but also stands very strong on its own unlike dark world
Age of Ultron - besides thor hot tub - stands alone?
Ant Man - nothing to do with IW.
3 nothings, 2 definites but 1 of which stands on its own very strongly and 1 scene in a movie.
I think he meant Fox making bad movies and making people not like CMB. I think Marvel has done a good job of making movies that just aren't CMB, they're more and I think this is why audiences have responded so well towards them.
