I guess accidentally stabbing your sister during a kickboxing match with Don "The The" Wilson does ease racial tensions, because everyone from the last film is buddies in this one! I guess they also forgot that Brad killed Johnny's cousin but hey the world keeps on spinning.
Don't worry about having to sit for an hour and a half while Don Wilson romances the ladies because this time some armed robbers have kidnapped her and taken her to an underground layer called Underground, so right from the get go Don is exercising those lightening fast feet by duking it out with gang after gang of homeless people while a DJ describes the action. Kind of like The Warriors, except the DJ here wants to give Don one in his tea towel holder.
So Don's going through this underground lair kicking everyone's arse's heads in while his mates Quan, Brad, Chuck (who seems to have gotten over Don stealing his girlfriend rather quickly) and ponytail guy mopping up behind him. And there's some bad guys who dress like they've walked off the set of Zardoz, great nineties hairdos, and the usual PM production values (people on fire, kickboxing, explosions
you know the drill). Oh, and there's a guy called Gimpy who likes blowing up stuff.
Fun all the way and everyone looks like they enjoyed making it, so this one's a given, if you like kickboxing films from the nineties starring Don "Corleone" Wilson.
