All the reviews i've read about it says that it is excellent and the best one since the first one. but anyone expecting wall to wall fight scenes will be highly disappointed, apparently it's more of a "character piece" giving closure on all the characters and what they've done.
Personally i can't wait for it, as long as it's got a good story with strong characters i think i'll like it. Oh yeah, and he better shout "Yo, Adrieeeennn" at the end, lol.
One final thing though, if the only time you've heard the Rocky theme is during those bloody annoying 118 118 adverts then obviously you are too young to remember, and shouldn't bother seeing it, it's nostalgic.
