I’m sorry but this show does NOT need cas!
It needs Dean and Sam.
Everyone else is a guest star – recurring or otherwise. Of course Mr. Collins puts time into the show as do all the actors that appear in it – it’s their job and what they are paid for! What a ridiculous statement! He would put in equal time to any other show he appeared in as a recurring guest. He isn’t going to turn down the pay cheque.
If you don’t want to watch if the angel goes no is forcing you to.
The show did great before him and it will continue with or without him.
As for brotherly angst – well it may be boring to you but it is true to life. The arguments aren’t the same just the same people having them.
The addition the show needs is a new storyline altogether devoid of angels.
Let’s see a new Supernatural being there’s enough of them out there that haven’t been used before.
