I liked "Point of No Return." If the arc had just been the first and last episode, I think it would have gone over much better. The giant explosion at the end was very interesting-looking and well done. There were some pacing issues, I feel, like R2's near-destruction and BZ's death which could have both been given more time. It was also cool to see Tarkin pop back up briefly, and apparently he's moved from Captain to Admiral by now.
Oh, and I also liked how the space station was based on the one from the new Star Tours ride. Very cool!
