Wow. Saw this one on TV after 15 years or so and I must admit it's one helluva piece of entertainment. Yeah, it has older-than-a-Bible James Brown,virtually no plot and non-moving actors like Lundgren and Nielsen....but,the last 20 minutes are hilarious to say the least. Drago(Lundgren)has a punch strength of about 2000 PSI,meaning his blows are twice harder than Tyson's, for example. He manages to hit Rocky in the head about 50 times and Rocky still survives 15 rounds. Not only survives, he wins and he even has enough juice to make a poignant speech. What surprises me is the amount of IMDb comments stating "well, it's not that impossible, when you're focused on something you can endure pretty much etc". First three movies in Rocky installment had somewhat credible storyline, although final fight with Clubber was fairly exaggerated. Here we have exaggeration multiplied by 50 : Drago kills Creed in round 2 and he uses same kind of attack on Rocky, he sends him 8 or 9 times on the floor and Rocky fights back for the first time in round 5.Come on, by that time he would have been already declared dead and received a Viking funeral.This movie is not all that bad, it has an excellent soundtrack and scene in which Rocky drives around reminiscing of his previous fights with "No easy way out" going in the back is touching, but fails miserably in department of plot development and credibility.Creed and Clubber were strong fighters but Rocky still had a decent chance against them, that made first three movies so believable. There's no way middle-aged midget like Balboa could have defeated someone with superhuman abilities like Drago...But I assume USA needed a patriotic boost in a midst of Cold War and Stallone certainly provided it with Rambo 3 and Rocky 4.
