Disappointing... The destruction of Marvel cinematic universe was not done by the hand of Thanos... it was done by the many hands of Marvel. There were some great scenes in this movie, although it was disappointing it was still entertaining. But there were also many unneeded, contrived scenes as well. The movie could have been a half hour or more shorter. For some reason we live in era where the length of the movie has become synonymies with greatness...
There were many scenes that greatly contradicted everything we know about the stones from previous movies including Endgame. The direction the movie went, in hindsight, seems more like a money-grab. The previous movie could have ended and tied things up more similar to the true canon of the books instead of continuing on what some may think was an endearing path to tie up the MCU. Closure. I guess you could say you get closure from the film, I did not. I felt in many ways that the ending was anti-climactic and the climax was delivered early on in the film.
I have been reading marvel since I was a child and have seen every film, usually twice in the theaters. The last Marvel flick I saw twice was Spiderverse which I loved. I was disappointed by Endgame... I imagine no-one else will admit this, but I will.
