They showed up in the Boba Fett Show, as well. I watched season 3 of The Mandalorian and decided that the show ended at season 2. Season 3 is kinda fun, but if you are binge watching there are a whole shit ton of immediate questions.
CGI Luke is dead-eyed, twice as monotone as Mark Hamill was on his worst unused take while filming ROTJ, and overall creepy AF, but he's fine until and unless you greenlight a project where Luke will be a significant character. You don't necessarily want to commit to whatever random was available to play either 1-scene "deus ex machina Luke" or 2-scene "plot-obstacle Luke."
