How significant will it be if BP is the first superhero movie to be nominated for Best Picture?

It will be a big freaking deal if it does. Some people don't think it deserves it, while others do. I'm the latter, it's not like Venom is getting Oscar attention. Sure there's The Dark Knight and Logan argument, but Black Panther received better reviews than both of them. 

Plus, it will break the CBM bias the Academy has towards them. This would be a good thing if Black Panther receives a Best Picture nomination.
