A fairly good point, but I still would add that there are people who enjoy PG-13 tentpoles who also enjoy other categories. I can see a lot of Suicide Squad viewers also having interest in movies like Sausage Party and Don't Breathe (strong appeal to young adults, who play a part in the box office of superhero movies), as well as Pete's Dragon and Kubo (families do go to superhero movies). Were they formidable foes? No. But could they have given a bit of a dent to Suicide Squad's potential performance? I'd say it's likely. And keep in mind that I don't think Suicide Squad has toxic nor phenomenal WOM. I just feel that it's having a simply okay run.
