It seems like the series is in fact getting better. I admit that they're still too short. I just really like the way this villain is designed. The voice fits perfectly too. You get a lot more of a story here. I think there is more characterization.
I don't see why they're labeled as being in space. They were always in space! Maybe I just don't know how that works. I like the name Xylus. Dexter is too generic.
