I had now few days to set my thoughts in order about this movie and the more I think about it the more I like it. It was an amazing closing chapter for the Avengers saga and a great send-off for Cap and Tony Stark. I will miss them, especially Tony in the future MCU, but the way they went out of it was perfect.
Every since I heard the first theories about time travel I was afraid that it will be done in such a way that it will steal from Infinity War's story, but the way they did it in Endgame not only that didn't diminish IW one bit but it even complemented the story. Killing Thanos in the first minutes only to get Thanos 2.0 as punishment for bending the timespace was nice.
I think Endgame also helped the more minor characters get a very nice arc. Nebula, Hawkeye and Black Widow all got their stories upgraded here and made them finally more useful in the whole universe. Especially Nebula had such an emotional roller-coaster here and I enjoyed every bit of it.
Fat Thor was a nice tension diffusing mechanism and I hope he will be in the Asgardians of the Galaxy. This and the "Hail Hydra" from Cap were a touch of genius.
There was less action overall, but there were several epic moments: Cap picking the hammer, everybody arriving through the portals for the final battle, the ride of the superwomen of MCU in support of Captain Marvel.
I have to see the movie one more time soon, I kind of miss it already.
