I just wanted to say for visuals, interesting ideas, the inversion of the original Star Wars plot its a decent episode and fun enough but I want to list three things:
1) The creators of this episode are playing around with a debunked theory that Lightsabers are extensions of force users proficiency in the force, so that gives a person the ability to throw their lightsaber energy around
2) Another kooky theory the writers are employing is that some Star Destroyers are so gigantic that they can have a gravitational pull and sustain some sort of atmosphere and therefore be warm and breathable in some way
3) This is "Japanese Star Wars" if you will so they aren't necessarily bound to our versions canon
If you go by these conceits, its an easier episode to swallow.
