If it's like Rocky 1 and 4 then yay! If it's like rocky 2,3 and 5, boo!
The script is really going to make or break it. As long as Stall One avoids the cliches and does something new and interesting with Balboa I'll go see it. That being said there isn't much untread ground for Rocky. They can always do what tanking franchises do and put Rocky in space. "Hey yo, I always wanted to fight martians, ya know, but I ain't to bright kid so Paulie got me this NASA job ya know and now I'm training in a space station...Yo Aldrin!!". But I know the premise already and it could be solid, it has potential.
