The writing is bad, and the characters are unlikeable. I don't mind the diversity casting, but the gang's personalities don't resemble the og characters AT ALL. Velma seems to be a know it all who doesn't actually know anything. They literally said she copies Shaggy homework. Shaggy goes by Norville and never says "like" anymore. Fred is completely rude and shallow. Daphne is a mean girl with anger issues. Scooby isn't even in the show! The whole show seems to be trying way too hard to be clever and meta. I can't tell if it's trying to be progressive or if it's making fun of progressive television. This series had potential and I really hope they do better for future episodes. I like the concept they were going for, and I kind of like the animation style too. It's just poorly executed so far.
Edit: I forgot to mention how much they sexualize minors. It's weird and uncomfortable. Maybe the characters will get better over time? Someone mentioned that it could just be a set up for character arcs but I'm not sure how you can start so far off and manage to fix it. It's probably too early to give a thorough review but it's already so bad! My boyfriend refuses to even be in the same room when I watch it.
