I had the same reaction. It made me realize how tired I am of superhero movies. Though I then realized that wasn't necessarily true because weeks later, X-Men: Apocalypse came out, and I was excited for that.

So, you're not alone, OP. And frankly, I hated Martin Freeman being there because he served no real purpose and I don't care for him in general. I also had no sympathy for Alfre Woodard's character because...it sucks that her son died, but you expect me to sympathize with her because the Avengers are the indirect cause of his death when y'all live in a world where aliens exist & supervillains are doing shit on the reg? Byeeee

Literally the only reasons I'm even excited for Spider-Man: Homecoming are because of cast members I like.
