Saw Captain Marvel and then immediately saw Endgame after the credits.
I thought that girl power moment was not done very well. I am not sure if I should say more as I don't want to spoil the movie for those who haven't seen it. I will just say that there is zero subtlety in social justice movement stuff.
Yup. It was a quite noticeable moment. But luckily seemed to really be the only big thing like that.
Captain Marvel however had a lot. They even managed to throw in an anti-Trump part in there, in a movie taking place in the 90's. Overall it was enjoyable as an MCU superhero action movie. Although I was actually pretty confused in the overall plot and how it fit in with what was already established regarding them as seen in Guardians of the Galaxy. The entire thing that they were doing actually made no sense and they never once actually explained why they were doing what they were doing.
Purposely being vague in order to not spoil anything.
I skipped Marvel and went straight to endgame. Missed nothing thanks to internet spoilers and trailers of Marvel.
Frankly, you miss nothing by skipping Marvel. The only thing to tie the two together is Captain Marvel herself. But the events that take place in Marvel have no overall bearing on Engame; no references to be missed or plot points.
