- Creative Differences: Between the franchise creator Masaki Kajishima and the series director Shinichi Watanabe. Kajishima hated the wacky harem hijinks and goofy characters introduced by Nabeshin,note as well as the handling of several his favorite characters. In the end, he even proclaimed the series non-canon, and retold the story the way he liked in a series of novels.
- Ear Worm: The opening song, in two languages.
- Moe: Amane as a kid.
- Nightmare Fuel: ( Upon taking control of the mech in Episode 24, Seina uses the force of his will to slowly crush a ship into a small ball, complete with a shot of the horrified crew. It's a very strange scene for such a lighthearted show.) Somehow made worse by the fact that the usual Awesome Music starts playing as it happens. Picture "The Rising Spirit" playing while Gaara crushes people. It's that much of a disconnect.
- Propaganda Piece: the Galaxy Police have a really bad recruitment film, with things like Scoring Points and even a grabber-claw enticement offer.
- Rescued from the Scrappy Heap: Seiryo Tennan. In the Tenchi OVAs he's an unlikeable fop who shows up just long enough for Tenchi to win a duel with him by default thanks to Mihoshi's bad piloting. In this series he's a credible threat and a genuinely likeable character, even if he is still a badass Butt-Monkey.
- The Scrappy: NB (and some other elements of Watanabe's humor) wore out their welcome with some of the audience. Officially? Well, in the crossover episode with the Tenchi Muyo! cast that Masaki Kajishima directed, NB literally spent the whole time in a doghouse.
- They Wasted a Perfectly Good Plot: Seina's total fear at the sight of Kiriko covered in blood and her pain at his rejection. Gets dropped faster than you can blink.
YMMV / Tenchi Muyo! GXP
