I've watched the whole of season 1.
Really enjoyed it and highly recommend it.
Totally looking forward to season 2.
What the plot lacks with its 80's styled cheese, and what some terrible acting just lacks, is more than salvaged by some of the funniest writing in Hollywood. Johnny Lawrence's character is just given gold jokes after gold jokes. The show is hilarious as the endless dead pan comedy jokes just reel off from his character. The jokes get funnier and more often by about mid season and they continue to hold their peak.
Johnny is the character that the writers are having the most fun with. His version of what happened with Daniel Larusso taking in the Karate Kid 1 film was the best tribute to the original films yet. Although Danny's massage gag (anyone who has seen the original film will sense when this is going to happen) was a fairly good tribute.
Put simply, this show is an adult brilliant social satire of today's world and of the 1980's, and a tribute (to the Karate Kid and the 1980's) comedy show disguised as a drama like the original films were that is made for a younger audience. For the drama elements, it is weak, it is predictable and it is cheese. For the comedy and tribute elements, this is like watching Ballers or Silicon Valley. It is that good.
The writers are the guys who wrote the Harold and Kumar films, and they have done a magnificent job with Johnny's character.
For me, Johnny is the star of the show. Barney from How I met your Mother got his tv show
