Having a bit of an inside view on Pentathlon (the sport! Not the movie), and a couple of friends who competed at Seoul, they swear blind it was nothing like this, and certainly don't remember Dolph swaggering (or staggering) around.
It's one for a wet Saturday evening, with nothing better to do, some beer, a pizza, a few mates and the sound turned down to create your own dialogue. I certainly wouldn't waste actual money on it though.
Only for die-hard Dolph fans or Pentathletes who want to include it in a collection for the sake of 'completeness' if not actual quality or watchability (more than once).
If you're an ice-hockey player, this film does for Pentathlon what 'Sudden Death' with the Muscles from Brussels did for that sport.
Mostly awful, but occasionally unintentionally hysterical. A true triumph of the 80's mindless cheesy action genre.
