Okay, I just saw this movie, so i shall give my official review:
[Spoiler Warning Ahead}
So, after harassing my parents to get to the theater early, (which they didn't do anyways) I was stuck with front-row seats. But other than that, things went off without a hitch.
As for the movie itself, boy do I have a lot to say about it. Although I heavily enjoyed "Infinity War", I found it to be a bit lackluster. But this film managed to rectify that and give me a nice payoff, as well as tie up almost every loose end in the MCU's arcs, even some that I had forgotten about up until that point. I have to say that my most favorite moment in the movie was the scene where everyone arrived to fight Thanos and the Chitauri in the massive war. The epic-ness of it all nearly drove me to tears as I finally saw every hero in the MCU unite and fight alongside each-other, a moment I had been waiting for ever since the MCU's beginning. I also got a kick out of the audience reactions; We all lost our sh!t when Spider-Man came swooping in! The scene with Captain America lifting Mjolnir completely caught me off guard, but I really loved watching it. However, the one thing i'm a bit disappointed with is that the Marvel TV/Netflix heroes didn't get the chance to join the final fight.
And as for the ending and Iron Man's death, it was really emotional, because I had grown up watching Tony Stark ever since I was 5. And even now, it is still hard for me to accept. But then again, this is a Marvel movie, so who knows...
Anyways, 11/10 I love it 3000.
