The first one for me was probably my favorite. It was kinda cool to see Tenchi's Dad get a little bit of the spotlight (even though it wasn't the perverted creepy dad we're all used to).
The 2nd one felt like it had potential. But after a certain jaw-dropping moment between Tenchi and Ryoko during an argument (if you've seen it, you probably already know what I'm talking about), I couldn't stop thinking about it for the rest of the movie. (I had just finished watching the last episode of Universe before I watched this, so imagine my reaction to seeing that right after.)
As for the third, I thought it was pretty decent. Tenchi with long hair took a while to get used to. Before I saw it, I had read that at the end of the movie Ayeka has a moment where she pretty much admits that Ryoko will be the one Tenchi eventually chooses. So I was HIGHLY anticipating this, but it didn't happen. Unless it was supposed to be when she tells Ryoko to go after Tenchi in the end???
