For my tastes yes. They've become long, repetitive, boring, homogeneous, repetitive, interminable, bland, bland, bland, never-ending, time wasting, monotonous, dull, deadly dull, uninteresting, unexciting, unvaried, unvarying, lacking variety, mind-numbing, mindless, soul-destroying, soulless, humdrum, dreary black holes of nothing but static feedback.
They're processed fast food movies with the imagination of a McDonald's franchise. Which wouldn't be a problem if they didn't seem to take up so much space and industry resources. The big fear is not that their jackboots are stepping over the small indie arthouse stuff (which they probably are to a degree) but that they are actually gobbling up the space of other more traditional and original blockbuster ideas.

Superhero movies are not really the problem though, it's the studios and their negligence.
