I still haven't seen Direct Action but I doubt that it can top SILT. That one is maybe his best movie (I can't decide because there are several that I love so much for different reasons). SILT has
- kick-ass martial arts
- a decent story
- an extremely good chemistry between the two leading characters
- good dialogues (something I really miss in many other movies of Dolp).
UniSol? Hm, the last fight between him and Jean-Claude is nice to watch. I'm no expert so I can only say what it looks like. Have no idea if it looks realistic or not.
There's not enough martial arts in his recent films I think. Wasn't Bridge of Dragons the last movie with a decent amount of unarmed fighting? Dolph with a gun is a waste of material, kind of. (Hm, ok, maybe with the exception of Men of War...)
