A damn fine piece of sentimental Hollywood boxing! Probably the best of the Rocky sequels (unless you have mad, mad love for the robot maid from IV.)
The fight sequence jolted my memory of something, though I couldn't quite place it until I got home.
IMAGINE: It's the grim, far future (of the eighties!) Mankind has so devastated the biosphere that civilization lives on only in fully contained arcologies ruled over by cyborg tyrants. Roving gangs of disaffected youth seek the only thrills they can find on illegally modified electric scooters. And the entertainment of choice for this dystopia (of the eighties)?
Well, take a look for yourself.
