I cannot for the life of me figure out what having diverse characters has to do with remakes being bad??
A lot of remakes are bad, hell, a lot of movies are bad, whether the characters are diverse or not. It's not the inclusion of diverse characters that makes films bad, and I can't even wrap my mind around the logical reasoning that would even connect the two.
Diverse casting just doesn't have the power to make an otherwise good movie bad...not unless the person watching is bigoted enough that just seeing diverse casting ruins an otherwise good movie for them.
Diverse casting also doesn't have the power to compensate for an otherwise bad movie, so with a huge amount of bad movies out there, I would just expect a hell of a lot of bad movies with more diverse casting as it becomes more common.
Also, the most legitimately woke movies I've seen aren't remakes, they're movies about diversity issues or are about diverse populations, and A LOT of them win awards: Hidden Figures, Moonlight, Parasite, CODA, The Big Sick, Get Out, Do The Right Thing, Guess Who's Coming to Dinner, West Side Story, In The Heat of the Night, 12 Years A Slave, The Theory of Everything, Ray, Girl Interrupted, Train Spotting, Peanut Butter Falcon, I Am Sam, Still Alice, The Fundamentals of Caring, Lawrence of Arabia, The Kite Runner, Malcolm X, Salmon Fishing in Yemen, Silver Linings Playbook, A Beautiful Mind, Rain Man, The Aviator, What's Eating Gilbert Grape, The Hours...
Just to name a few...
