What's with all the hate?

Rating: 10/10 (1 September 2019)

Just wow, i read things like:
"it's just so cheap to mess with time, then why they don't kill thanos so endgame doesn't even has to happen 1/10". - Did you even watch the movie? (actually a lot of people said that i honestly can't believe it)
"Overrated, only marvel fans will like it 1/10" - It's the last of 22 movies, if you don't like marvel im guessing you don't like the other 21 movies, so what are you even doing here?
"it ruined thanos and the heroes one with no casualties like every superhero movie 1/10" WHAT?
And literally tons of senseless 1/10 without even writing something, just pure hate.
I could go all day but no ty.
My review:
I know it's not a perfect movie, but it was good. I liked it.
