....I don't know that I'd call that a debate.
But let's break it down anyway, point by point. And I will keep it civil.
Like Athanasius said before, Ayer is a one trick pony. Look at his career,
Sabotage: A dirty DEA agent taking on a cartel
End of Watch: Bad cops taking on gang members
Street Kings: Dirty cop taking on drug dealers
His resume is a tome of redundancy.
Christopher Nolan has not only created critcally-acclaimed, thought-provoking films like Memento, Inception and Interstellar, he created what is widely regarded as the best adaptation of Batman to date. His films are as well-orchestrated as they are original.
Like Tim Burton, EVERY director is famous because of their unique style. If that weren't the case, there wouldn't be powerhouse directors like him, Nolan, Spielberg, Columbus, etc, etc. Burton presents a gothic style to normally average and mundane settings. Films like Beetlejuice and Edward Scissorhands would be completely flavorless without Burton's particular flair. No other director could achieve what he did with those films. His version of the Bat-verse is, to this day, still the most iconic and recognizable. Casting Michael Keaton as Batman was a stroke of genius as he set the golden standard for the role.
Leto is one of the most overrated actors working in Hollywood. He is an overactor has no on-screen sincerity. His best role was in American Psycho, because his character was fake and had no real interest or connection with the people he interacted with. It was the perfect role for him because he didn't actually have to act. I have no real explanation as to how he hamfisted himself into winning an Oscar, but the Academy Awards have been so politically driven rather than talent based for the last 20 years, that an Academy win holds as much weight to the average viewer as an MTV award.
I don't get tired of hearing the truth. I get tired of always being right.
