I'm a snyderverse fan so I'm disappointed there are no more Cavill and Affleck movies. I'm guessing that at some point when Gunn became the DC guy planning out things, had the conversation with the both of them about how zaslav was going to reset the universe budget wise, basically cutting out big names like them. I mean WB has even been canning movies that were basically done to save money somehow. Sorry to see them go, but go ahead and get a paycheck from someone whose gonna pay what you're worth.
I do like Gunn, he's Troma alumni doing mainstream movies, which still sounds unbelievable to say, and I enjoy his stuff. I'm interested in seeing where everything is going to go. I'm sure it's light years ahead of anything marvel is necromancing to shove down its viewers throats.
