Seriously?

That's like saying "Aren't people tired of Sci-Fi or Fantasy movies yet?". To put it bluntly, these superhero movies are the only thing keeping Hollywood relevant in my most peoples mind. Horror movies have been garbage for many years, action flicks are just rehashed sequels from half-dead franchises like Fast and Furious/Mission Impossible and I am pretty sure Hollywood forgot how to make comedies. Not to mention the over saturation of remakes/reboots of older movies to introduce the Millennial generation to them.

There's a reason Netflix is so huge...people are still going back to watch movies from 10, 20 and 30 years ago because most movies now are terrible. Why are superhero movies, wait I will rephrase that to comic book movies, so popular? Because comics are one of the last few creative mediums out there.

Obviously you don't enjoy comics, but just because no one else is making good movies doesn't mean others will get tired of the one bright spot.
