The difference here is that at least in III, the first third of the film is over the top on purpose to show us how far from reality Rocky is, until his defeat brings him to down to earth, and the rest of the film returns to a reality closer to where we had been before (though Rocky is still inexplicably smart). IV is pure cheese from frame one and never stops. The Cold War is fought and won by Stallone, but not before some pretty clichéd training montages, complete with that "Hearts on Fire" 80's relic blasting. Oh, and can we mention Paulie's new robot? Hate Part V all you want for almost ending the series on a slight downer, lame Don King-esque characters and all, but at least it didn't feel like a cartoon.
