Saw it this morning and I really loved it. Can't wait to see it again. I thought the humor was about the perfect amount and loved all the nods to the MCU i.e. the driver being named Jarvis. People already have mentioned it but the "Hail Hydra" line was great.
The first hour wasn't problematic to me. How often does a movie come out and it's all about explosions and CGI with no story or character development. I thought it was refreshing and considering it's the last chapter for some of these characters, the first hour was worth it.
I guess I expected more deaths, not that less deaths was disappointing. Never saw Black Widow dying in a million years.
This (these) movie(s) have a ton of heart and that's why Tony's death hits you so hard and Captain America coming back as an older man who will no longer be part of the Avengers has a huge emotional impact. Any movie can kill off a main character but if the audience doesn't have an emotional connection/investment to the character then who cares? It would just be done for shock value. Maybe it's a little unfair bc nobody has the opportunity to build a 22 movie literal cinematic universe of character development and audience's emotional investment, etc. Tom and RJD knocked that scene out of the park.
Thor's personality being different didn't bother me. He was quite a different Thor in Ragnarok so the change in character in this movie didn't seem out of place to me. I really hope he is in GOTG 3 bc the scenes we have seen so far where he interacts with the Guardians are incredible
In IW I really thought Red Skull sounded like Littlefinger and I feel the same way after Endgame. I'm familiar with the actor bc I've watched The Walking Dead, idk it's just odd to me that Hugo Weaving gave Red Skull a bit of an accent befitting where his character is from and Ross Marquand does an accent vaguely close to Littlefinger's (maybe a hint of Norn Ir'n in there).
