Been working on watching all the main Marvel movies in preparation for Doomsday (I've seen it referred to as "Doomsday Prepping"), I watched the last one on my list yesterday. In hindsight I wish that I had watched them in order (I saw Endgame before Infinity War, Brand New Day before No Way Home, GotG3 before 1, etc.), but I guess then I wouldn't have gotten to see some of them in the cinema. I'd say Infinity War is my favorite, although the first Iron Man is a close second.
Doomsday better be good.
