I only watched The Book of Boba Fett so I can understand what happened to Grogu's training between Mandalorian season 2 and 3.
Damn, that Boba Fett serie is bad. It's even difficult to watch. It's so slow and badly written. It looks like some executives at Disney's said Let's do something for teenager and let's put some colorfull and shiny scooters, they gonna love it. Anyway, the only good thing about each episode is the production drawings during the generics. :(
