Its one of those 'depends on my mood' choices this. Both are really good; but The Wrestler is the more original. Balboa is just a rough remake of Rocky, with age replacing inexperience. I can't see how Rocky Balboa can be praised for it's feel-good knockout punch - every Rocky films got one. In fact, Stallone's built his career on 'brave feel-good knockout punches'. He stuck one in Get Carter, and look how that turned out. Sly got blood out the stone one last time, but The Wrestler's bleak originality wins out for me.
