I will say my criticisms don't ruin the movie for me...despite it being a plotless bore overall, I did get some enjoyment out of it

Certainly not as "jokey" as I was expecting it to be, which is always a plus, but when the jokes did come they were awful. Peter was basically nothing but a pop culture index, what is he from, Ready Player One? I don't know who does "I don't want to go" better, Tom Holland or David Tennant (oh I am a cruel one)
Gamora almost stole the whole movie for me with the scenes she had, and Brolin poured his heart out as the emotionally spent but driven Thanos trying to justify his perspective on life to all of those desperate to stop him.
Then there was how rushed Wanda and Vision's romance was...like I get that a lot of time has passed and we got some explanation with Rhodey and Ross's meeting, but it still seemed out of left field.
There's more I can list, but they're the ones coming to me right now
Should also point out that my theater was void of any emotional reaction...very neutral responses, polite laughter at the jokes, and deathly silence at any casualties.
