Film didn't serve a purpose.
Nah I can't agree. I didn't like "AOU" at all but:
1. First time the Avengers acknowledged the Infinity Stones.
2. First time Wakanda was referenced.
3. First appearance of Black Panther villain Klaw, which set up that movie.
4. First appearance of Vision, who obviously plays a key role in "Infinity War".
5. The events lead directly to "Civil War".
I'd say the main problem with "AOU" is it served too much of a purpose, plot-wise. They crammed so much shyt into the movie setting up the next Phase the movie itself suffered.
