Tbh, I'm rather tired of the Marvel Extended Universe and I also think people are tired of this superhero movies as a whole. On one hand, it seemed the latest Superman movie did ok, but not when taken in the vein of kicking off the DC universe. I heard some people liken it to another iteration of guardians of the galaxy, i.e., that's all James Gunn seems to do these days. When that was said, I can't unsee it.
Everything needs a universe these days, everything is setup as a franchise, paving the way for the next iteration instead of just making a movie that is fun to watch, that preach and is a good diversion to the stresses of life.
