‘Cobra Kai’ hasn’t lost its kick as it keeps ‘Karate Kid’-ing around

Crossing the streams with its sequels, the fifth season of “Cobra Kai” features heavy dollops of the second and third “The Karate Kid” movies while continue to carve out its own next-generation melodrama, all in extraordinarily nimble fashion. While it’s not the best series on TV (OK, Netflix), there should be some kind of prize for the best revival culled from limited source material.
