Same. I enjoyed Infinity War a decent amount, but Endgame didn’t quite sit right with me for some reason; maybe because it felt like the pulling of strings to make the narrative fit certain things was more apparent. Lost all steam after that

I lost interest after the first Iron Man movie.

I wouldn’t say I lost interest, but rather that Endgame was a great ending for the MCU. Why would I want to watch past the end?

Endgame was a clipshow which was a let down for me. That was my step off as well.

I still enjoyed the latest Spiderman but the rest seems quite uninspired.
