Marvel and DC have taken comic books for kids and turned them into an unstoppable machine, designed to entertain the masses while making massive profits.
When all the pieces fit together, it’s memorable and magical.
When they don’t, as in SUICIDE SQUAD, everybody notices. (Warning: this is packed full of spoilers.)
It’s like making chocolate chip cookies: Marvel and DC have well-known, well-liked ingredients that people have loved consuming for decades.
Mix it up, put them in the oven and serve them warm and hot. People are going to eat them. It’s not rocket science.
HOWEVER: your average person has eaten a lot of chocolate chip cookies, and seen a ton of these comic-book movies. They’ll know, right away, if Marvel burns the whole batch or DC forgets to add any chocolate chips at all.
