Aside from the majority of this post being irrelevant to Endgame...
None of the threads are 'overrun' by Captain Marvel "haters". Rather, people who find her character for what she is (bland, mediocre, sidekick), are berated for their opinions rather than simply accepted (and moved on from).
I said that Captain Marvel is a mediocre movie and was immediately attacked by people with agendas that I simply could not care less about. No one's opinion is more valid than mine, and to argue otherwise is entirely asinine.
Captain Marvel's mediocrity was absent for a long stretch in Endgame and it allowed fan service to pay off. I had the largest sigh of relief when she said, "you won't see me for awhile". I knew the Russo Bros. were doing something just. It gives a very long stretch of well-acted characters with connections to the audience and focuses on the nostalgia of the MCU.
