How bad is it? Bad enough that some think it must be intentionally bad.
Should you see it? Yes.
I admit I'm no expert on martial arts films, but a few people pointed out this film as one of the more entertaining terrible ones. A potent drug causes a guy's overdose, so the guy's brother goes to Hong Kong to learn kung fu (neglecting both the family business and his fiancee). Bolo Yeung gets top billing on the box, but he's only in about 3 minutes. Jamie Farr (!) has more screen time, with his old Lebanese accent (for comparison, check him out as Jaleel Farrar in "Arnold" in the 1960's) getting thicker at times. The main character's so short that he looks silly next to his girlfriend. There's a training montage that looks like a dance party. There's a death by toilet seat. There's a cartoon fart (I won't explain). The highlight is a fight in the back of a moving garbage truck. The dialogue is incredibly bad, the one actress is a non-actress and there's some very silly fights and weird-looking characters.
