For real. You need to go through 7,400 different comic books, shows, and movies to even start to catch up. No idea how people can shit on Star Wars for milking the franchise when this fucking abomination of media exists.
That's absolutely false, the fact that you say this proves that you really don't know what you are talking about.
I bet you came to this conclusion because you probably watch one random reunion movie in the middle, like an Avengers movie, without having seen any others, you didn't understand it, and you assumed you had to have knowledge about everything marvel to follow it, but that's not true.
The Marvel Cinematic Universe is its own thing, it's not canon with any comics or other Marvel Medias, and some stuff in these movies don't happen like they do in the comics anyway, they are really not related.
The only thing you need to be able to follow this saga, is to watch the MCU movies, and that's it.
Yes, it's a lot of movies, about 23 for the main "infinity saga", but it's really not a problem if you are into it, the movies are great and are all connected very well in a consistent, logical way, it's just like watching a super high budget show, with 23 episodes of 2 hours.
It's in my opinion an amazing thing that this project even exists, it's the best adaptation of a "comic book style" that could have been made in movies, having a large scale world with so many different things, all connected in one coherent saga.
It might not be for you, it's not for everyone, but it's moslty perfect for people who do like super heroes / comic book styles, and what you said in your comment was just a wrong assumption.
