I got the feeling media has been saying “people are over superhero movies” for quite a while. Eventually it had to “come true” as Marvel has turned down the stakes and mostly focused on some cheap (relatively speaking) tvseries that probably nobody but comicbook fans watched, and some movies that are connected to these, with less known heroes.
They’ll be back again for Deadpool, Fantastic Four, and Blade, and the “over superheroes” trend will be forgotten. Again.
