Just finished binging season 2. Much like S1, it continues to be a fun, light, highly enjoyable series with great characters, terrific acting, and plenty of 80s nostalgia. Johnny really is the heart of the show at this point and William Zabka's performance is excellent. Macchio is pretty solid too, but Zabka just steals every scene he's in.
Most of the kids are quite likeable as well. It was also a treat to see the return of Kreese (Martin Kove) and Johnny's old Cobra Kai gang from '84.
