I think the boards have just gotten ridiculously elitist. "Oh, he's the star of a TV series and you're suggesting him for a big screen role?... Well, **** him, his life and his entire family, while we're at it."
1989 - "That Batman movie was pretty good. I wish we had more comic movies..."
2015 - "Aunt May is too young, Aquaman isn't blonde, Apocalypse looks purple, and ALL THESE ACTORS ARE TOO SHORT! HOW COULD THEY DO THIS TO MEEEEE?!?"
