Interesting idea, but it is essentially a different take on the "Do video games make children violent?" question.
Also, there's a typo in the headline: it's the MCU and the DCEU. (I wasn't sure if the paper had it incorrect, too, so I checked; only the headline is wrong.)
EDIT: I'm curious about the downvotes. We all (as educated/informed adults) know that the video game reasoning is false, and has no real connection to making a child violent later in life, right? Or was it because I pointed out the typo that is still showing in the headline for me?
