Henry Cavill may not be Superman

Problem is the more you give people what they want the more likely it is that the audience becomes overly familiar with it all and is just no longer interested.

Similar problem with TV shows if the first ten episodes don't hit high enough ratings they give you the axe, so there's no time anymore for a show to grow and improve. If don't make a instant impression they're just not gonna do much about you. It means second chances are at a disadvantage.

Superman movies are like Hulk movies. People seemingly want those, but actually they are not.

Hulk and Superman are probably too well known to be interesting anymore.

DC needs to move on to the famous yet relatively unknown characters, like Wonder Woman and Flash (just like Iron Man, Thor, etc.)

Or...

Please bring out NEW unseen before stories in live-action movies, like Flashpoint, Injustice, Blackest Night, Kingdom Come, Bizarro World, Justice League Dark, etc.

I would see ALL those universes if they made them into live action movies.

Give up the "cinematic universe" thing to Marvel already. They can cast different actors for different universes so WB won't have Disney's problem of aging and increasingly more expensive stars. They also won't have the problem of super convoluted inter-connected storylines.

They can't wait for him forever, fans are just setting themselves up for a possible disappointment by staying put. A superhero movie can't be written around an actor because that would lead to some massive issues and end up with something that is utter garbage.
