Actually I'm getting burned out. The same thing is happening in the MCU that happened in the comics. Just too much. I mean yeah, folklore is one thing. Those are the unifying bits of cultural mythology that bind. Everyone at this point knows that Batman will always lose his parents, Superman is the Last Son of Krypton, and Spider-Man will learn with the Machiavelli quote. That's one thing, that's how come I can watch four Batman films and unless it's just bad generally enjoy myself because it's like Beowful or John Henry, or Cinderella, everyone know the key points.
But keeping up with a narrative continuity spanning one TV show like a dozen films, and two Netflix series (of which I'm locked out of because I can't stream TV shows) is growing beyond the ability to actually support it on the silver screen. It's one thing to have your tome of curious and forgotten lore, but it's another to keep butts in seats for more than three hours tops. It was an ambitious project and a great feat, and I'm glad it looks to be ending at Infinity War, because if it doesn't end, it's going to implode.
