I had initial reservations when the show began, but I quickly became invested after experiencing the first season...! There were humorous moments alongside a good amount of action. The tone felt considerably darker than what was presented in the movie sequel. The second series began hinting at moral ambiguity; it seemed to suggest that there aren't clear-cut answers, but rather shades of gray. However, season 3 really elevated things! And the last episode...I was truly astonished! I was particularly impressed by the two large-scale fight sequences: one featuring Miyagi-do pupils and former Cobra Kai students united against their Cobra Kai counterparts, and another with Lawrence’s confrontation with Kreese followed by LaRusso versus Kreese. The series as a whole reunited several recognizable characters from The Karate Kid franchise—connecting older and newer casts. I am eager to discover how the story ultimately resolves!
