There is alot to be said about this show. It is awful. I certainly don't recommend to watch. You waste your time. You don't really make any sense of what's happening. If you already seen the 3rd season. You don't need to watch the 4th season at all, because most of the plot is reused from season 3. The whole plot of this series is literally about alternate Tenchi Muyou universes series characters while reusing plot from the original trilogy. This is not Tenchi Muyou Ryououki anymore. The main characters barely exist in this series. The only thing that exists is maybe the Tenchi residence. The way theydo it is by cutting everything the show had good in it, starting with the main characters, with the art itself, and by literally throwing dialogue as a main plot device, to introduce a new main character in the place of Tenchi. The original characters have little to nothing to do with this show, while there are introduced up to 20 characters per episode.

The art was wholly digital, and the old Tenchi drawing style was redone into a new one. Most of the characters where copy paste with few alters. Colors were poor. Very few shades were used. Contours, what are those. The backgrounds where redone as well and because of that we won't be seeing but few residences, most of the time - Tenchi's.

Sound was obviously poor. I am ashamed to hear this. The intro and the outro changed the whole tonality of the show. They don't have anything to do with it really.

The story is awful. There is nothing but too much dialogue with little to nothing about anything that really matters in this series which is hard to follow and make sense of it.
