I bought the 4K UHD set on release date. I watched it the next day (yesterday). I had watched Infinity War and Captain Marvel on Sunday and Monday (3 and 2 days, respectively) before.
I enjoyed Endgame, do not regret the purchase, BUT -
Captain Marvel was very politically correct, as was End Game. Nothing objectionable, just contrived and gratuitous.
Endgame just didn’t grab me. It was flat, if I might repeat a comment from a recent post. Perhaps I was affected by too much MCU in a condensed timeframe. While I was entertained, I walked away VERY disappointed, and my expectations were not high.
I felt that Captain Marvel’s place in the story was under developed and Thor’s was a mockery. Kind of like Disney said “hey, we can’t have a macho male as a hero, so let’s create a female replacement hero”, and of course make a couple bucks with the additional movies. Admittedly, they did it well enough that I cheered inwardly when she arrived in the final battle!
As for comments about audio and video, I’ve nothing to add - just to confirm it was mediocre.
I hope my appetite for super hero movies returns, but I’m burned out for now. It might help if the actors would refrain from telling half the country how they hate us for faults we don’t actually possess.
