I enjoyed this much more than Infinity War. This felt like it took its "culmination" responsibilities very seriously. It judiciously exploits the character goodwill built up over 21 movies in a way that makes the audience feel recognized. I'm not sure about some of the timeline stuff, seemed like it contradicted itself a bit on that front. The [redacted] was an amazing surprise but very little in the grander story acknowledged the ramifications of it. Overall though, a pretty stunning achievement.
I gotta admit I struggled a bit with this - don't tell anyone. It was only by about half-way through that I accepted what this film was trying to do, and from that point onwards I was fully with it. I might've been in the wrong mood for it. Ultimate response is one of admiration more than pleasure.
