The movie IS a part 1 but it holds it's own just fine just like Two Towers or Empire Strikes Back. I don't agree with the criticism at all on that front.
Comedy was the weakest part imo. Not because it had too much, at this point I expected more than the movie had so I was gladly surprised, specially for the last act. But because it was not funny at all in a lot of exchanges. The only ones that made me laugh were the Guardians and Thor.
There's a lot shyt going on but I'm so invested on the characters and story that I had no issue with it. It felt like a big epic and it was exactly that. A whole bunch of cool scenes and fights and I DID NOT see the finger snap coming.
Thanos was incredible, I didn't think a CGI character would get to me like Caesar again but damn, Brolin and the special effects department did it
I need a gif of Banner in the Hulk Buster at the end, that shyt had to be the worst CGI ever on a Marvel movie, it was so bad I couldn't help but laugh at it. He was on the backround but holy shyt was it bad
WHAT DID STRANGE SEE??
Lastly, I knew the post credit had to be Captain Marvel but the nerd in me still had hope that the signal from Fury was going to say "Fantastic Four", I know that it was practically impossible but I just couldn't help it.
They would've taken the gauntlet off him but not kill him or something.
I agree power levels were all over the place as they had to adapt them to who he was facing but that's a regular issue with comics and everytime you have an overpowered dude. Maybe I've seen too much DBZ and Dragon Ball Super that I don't care much about this sorta thing if the story is compelling - and I thought it was in this movie - but him getting trapped by Stark, Strange and the rest wasn't that far fetched, Strange is powerful as fukk and the rest just followed a plan to distract him so Mantis could do her thing...and only for a bit because he was too damn powerful.
You gotta make Thanos somewhat vulnerable and even though they took some leaps in power levels, I didn't think it was that bad. in that case.
Cap being completely fine after getting punched in the face was WAY more egregious imo.
