You're such a mong.
For starters, the article says that the 'possible but inconclusive' signs of fatigue are "a trend worth monitoring" because of "aggressive investor expectations." It doesn't say a fucking thing about investors being worried about superhero burnout, it's saying that they have to be mindful of anything that could impact the bottom line because investors expect these movies to be cash cows.
I also like how you pick a single paragraph out of the article and ignore the one where the studios rebut the 'possible but inconclusive' fatigue claims by citing the interest in upcoming superhero movies, and you also skipped the multiple paragraphs suggesting Trank was largely to blame for the movie being a flop.
So yeah, shut up.
