but I just kept thinking 'why' during the show over and over. I'm a big MCU fan but I think thy haven't made much that has been top-tier since End Game. It just feels like mostly setting up new characters and just checking boxes more than trying to really tell great stories.

If you enjoyed the show please tell me what you liked about it. That would help me out. I may be being too critical about it. I think it's mostly that the TV shows have smaller budgets that don't meet the CGI standards of their films (which is probably why they couldn't make Eternals a series instead).
