Is anyone fed up or getting superhero movie fatigue? Not me. I hope the MCU carries on and on for a long, long time. As well as the DCEU grows and makes more movies and becomes as successful as the MCU. I do not see myself ever getting tired of it, though I do think more than 3-4 superhero films a year can be tedious.
I am excited about the upcoming films like Auquaman, Captain Marvel & the as of yet unnamed 4th Avengers film. I hope there will be a Ben Affleck Batman movie (or 2 or 3) and we are going to get Shazam, Wonder Woman 2, Cyborg & The Flash as well a new reboot Green Lantern film as well by the time 2020 is done and dusted. That is good pacing.
Unlike a lot of fans I never was a big comics fan. I read some Superman, Batman, a bit of the Avengers, some Iron man, Thor, a bit of Green Arrow & Green Lantern and The Flash as a kid. Spiderman on tv as the cartoon but never read many comics and watched Batman & Superman movies and Wonder Woman on tv. I had never heard of Black Panther, Dr. Strange, Deadpool, The X-Men, Captain Marvel etc until the movies were announced. My superhero was the Phantom, whose comics were very popular in India and which I read after moving here back in 1987.
