Endgame is a great popcorn action movie to "finish" a saga of popcorn action movies. This isn't serious entertainment and shouldn't be considered as such, and it reminds me of how George Lucas made Star Wars as an homage to the cheap serials like Flash Gordon. Especially as comic-sourced material, this is what the MCU is. Some part of me is actually a bit pained to like it as much as I do, given that it is just playing on base emotions to make money for a massive conglomerate like Disney.
