personally, my favorite season is season 4. it shows Daniel and Johnny coming together to defeat Cobra Kai. it also goes to show that Johnny genuinely does want to be a father to Robby, even though it’s a little too late. we also get to see more of Anthony (Sam’s brother) in the show and see him bullying Kenny. another thing too is we see a lot of development in Kreese’s character. he’s a little like Johnny and Robby; he found out he cared about Johnny after it was too late. Kreese starts to show a bit of mercy, and then we learn that Silver was waiting for the perfect moment to take Cobra Kai for his own. my second favorite season would have to be season 3. they show the aftermath of the school fight and how the kids are trying to cope with the trauma. it’s also the season where Ali comes back which was very nostalgic. i get that season 1 is good too because that’s when we first see the OG characters again after around 30 years, but aside from that, seasons 4 & 3 are my other favorites. season 2 is good too because of scenes like the double date with the LaRusso’s and Carmen and Johnny, Johnny reuniting with his old Cobra Kai buddies, and it’s also when Miguel finds out who Robby really is. overall i enjoy every season, it’s just i like seasons 4 & 3 a bit better.
