I say it again - they should’ve ended things at Endgame, and a Phase 4 should’ve only been for any plot threads they needed to tie off.
They’ve gone through every character people give two shits about, and every big name in Hollywood that isn’t borderline geriatric has been in this franchise. They could’ve Vaulted the MCU and break it out as a Collectors Edition whenever they were having a Bad Year, and then maybe in a decade start the whole thing over with a different overarching plotline - lord knows there’s enough material to choose from.
Instead, the Rat decided to get every last drop of blood they could from this stone, and it’s just fun to watch the train wreck.
