I watched all of the Tenchi Muyo!, Tenchi Universe and Tenchi in Tokyo series after 11 years earlier this year. I also watched the movies: Daughter of Darkness and Tenchi in Love 1 & 2.
I'm assuming this is one of the few times anime comes before manga
Tenchi Muyo became weird and boring after the Kagato saga:
1. They had an episode about a baby
2. They had an episode about Ryo Ohki getting lost in the woods
3. They had an episode or 2 about a random Android sent to kill Tenchi and instead falls for Tenchi. Somehow this Android is more powerful than Ryoko (even though Ryoko has the power of the gems of Washu which means she can destroy a planet with all 3). I guess Android 17/18> Vegeta but still, it doesn't make sense in Muyo because Washu is still more powerful than the Android
4. They had a huge episode gap (several years) after 'Here comes Jurai' and it wasn't anything to do with Jurai
5. Tenchi's Sister is in her 80s which means their Dad's in his 200s. Tenchi's Maternal side is Jurain, not the paternal side. If it was true wouldn't he all be like 'wtf,my Dad's over 200 years old'. Plus it means the Dad and Mom are related
6. Washu can already beat everyone
I still don't understand why there is a counter-actor and why it is Aeyeka/Sasami's Mom. There is no explanation for it at all.
