Definitely agree with everyone one seismic charges. Unlike the ST, this show knows how to do it right. They seem to understand the difference between "fan service" and simply doing what is right by the fans. Fans waited 40 years to see the OT cast on screen together again, and the ST passed on it. Could have been the biggest theatrical win of all time, and imo cast a shadow over the trilogy from the start.
This is something Lucas understood as well. When Clone Wars brought back Darth Maul, a lot of people (including myself) initially thought it was cheesy fan service. But it turned out to be a well done, excellently crafted plan and one of the best storylines in Star Wars. It was simply doing something right by the fans. And now we Dave Filoni and Jon Favreau continuing that with Boba Fett, Ahsoka, and even Bo Katan.
