Having a little or no idea about the previous movies, I decided to give this a shot. It's one of the best decisions I took.
Cobra kai is a series of all emotions, where the show will inspire you in one way or the other, show you the balance in everything. It will put you in a spot where it becomes difficult to choose which side you're on, because every side has a sympathizing storyline.
The fighting scenes, the acting, the sets and the story are all on point. Not only does it stay connected to its original matter from the 80s, but also makes you think it's a completely new show with so many perspectives.
Give it a shot. You'll not regret it.
