It’s a bit subtle, but Jeph Loeb does seem to take a small shot at DC here, implying that Marvel’s work is already superior, and as such he doesn’t have a lot he can learn from Suicide Squad.
Regardless of how the people at the two studios feel, there is a perceived competition between Marvel and DC films.
Suicide Squad failed to match the box-office numbers of Captain America: Civil War and it also fell far behind as far as the critical reception.
If Marvel isn’t paying that much attention to what DC is doing, is it really worth the rest of us spending our time comparing the two?
