I might have to give this a try. I too want to wipe my memories of TLJ, plus I actually kind of enjoyed RotS (call it a guilty pleasure) which I believe takes place not long before that movie. It'd be like one giant RotS prequel. Moreover, I just miss seeing actual Jedi in Star Wars.
I highly recommend it. The first two or three seasons are a little bit slow but the later seasons are just amazing. And there is plenty of lightsaber fights in it!
