The only MCU movie I watched in the theaters was Captain America. I had seen Iron Man and Thor on tv or rented them, but I was never "into" those movies back then, and had no idea they were all connected. So I wasn't part of the masses that watched them all when they came out in the theaters over a 10 year period. I went back and started with IM1 and watched them all pretty much for the first time on D+ in January 2021 when I was sick with covid. And that took about 10 days. Trust me....Endgame had an impact on me.

Yeah, I binged watched all of them back in January 2021 when I had covid. I had seen Iron Man, Thor, and Captain America many years ago, but I never really got into them and had no idea they were all connected. So starting from the beginning and watching them all in order was extremely entertaining.

MCU. I was blown away watching all the films in order for the first time a few years ago. The culmination of the first 3 phases ending with Infinity War and Endgame was just brilliant. Quite possibly the best series of movies I've ever seen that are interconnected.
