There are 5 seasons of a tv show based on the karate kid movie?
Oh yes! And it's not bad actually. I suspect they will wrap it up next season though as this season resolved most of the outstanding plot lines with antagonists that go back to the movies no less:
1) Terry Silver - in jail.
2) John Lawrence - changed his ways and is a good guy (really he changed at the end of the first movie so this is pretty logical).
3) Chozen from Karate Kid 2 - changed ways and became good guy (although he should have been in jail from events in Karate Kid 2).
4) All that remains is Kreese (Martin Kove is great as this villain) - I suspect he finally changes heart.
The whole series is a giant series of redemption stories so to speak.
