The Stranger Things-ification of Movie Posters

How come every movie poster looks the same now? Like over-bloated, photoshopped collage where every character in the universe is crammed in.. 

I can't help but blame Stranger Things for starting this trend
My evidence: ST Season 1 poster (the rest of the seasons followed this formula too)

Now look at every movie poster ever and you won't be able to unsee it
 

Just another art form ruined by the Duffer Brothers!!!! #BringBackArtisticMoviePosters
