Hahaha! Don’t think I’m criticizing. I contemplated doing it before Infinity War, at the encouragement of my boys. My younger one even sent me the following link to all past and known future movies:

Infinity War was #19. I just couldn’t see taking the time to watch 18 movies (most of them I’d seen) in preparation for it. Not sure what my number would have been, but with maybe only 6 or so, I would have...
Captain Marvel will make #21.
Well, one reason my list may have been shorter is that we didn't watch any Iron Man movies. Tony Stark is my least favorite Avenger and I just don't care for an entire movie of him, or 3 entire movies of him. Also, I am not a big fan of the Ant Man series, although, I will admit that I have watched both movies and IMHO the Antman/Wasp movie was much better than the original. I think I watched it because I knew that it would be connected, somehow, to the Infinity War story. I had to wait til the little extra scene in the middle of the credits to get my connection. Also did not watch Spiderman.
So, those exemptions would bring my list down in number.
