Ralph Macchio is back as The Karate Kid...and yes, he does still look like a kid! The guy’s found the fountain of youth! A new “Karate Kid” spin-off TV show called “Cobra Kai” debuted yesterday on YouTube Red. The story is set 34 years after the original movie and brings back Macchio and his arch rival Johnny Lawrence, played by William Zabka (remember the leg-sweeping bad guy from the first film?). In the new series, Johnny is basically a loser, and Daniel LaRusso (Ralph Macchio), is a successful businessman. Cobra Kai has 10 half-hour episodes, and it's getting pretty good reviews! Here’s the trailer!
