Not the best star wars entry, but no way near the worst. I have a few issues with some of the characters not feeling very well put together, and some of the dialog is a little clunky, but that actually us fairly normal for star wars.
However, I do feel the moments the show shines, it does so very well. Some of the best lightsaber fights we have seen, and possibly the coolest live action baddy since darth maul.
Overall I would give this show a solid B grade. It has its good and bad moments, but I feel the overall good moments outweigh the bad ones.
