Part III is rough. Danielle seems all hopped up on speed throughout the whole thing. He and MiagiDoKarate open up a banzai tree store. At some point Danielle gets trained by the villain and has to take some lumps. There is some sort of blackmail or something going on. Its been a few years since I've seen it. It is worth seeing for its crappiness alone. It does not hold a candle to I or II.
I watched Karate Kid Part II the other day and it brought back some great memories. That movie's not bad. For the life of me, I can't remember Part III...
Dubbed an old tape to DVD yesterday and this was on it. I got sucked in, spent about an hour watching the old grainy taped from network TV version. Made me realize I need to get this on DVD.
