*sighs* I have to begin by saying that I adore the original OVA. So, this review might be a bit biased.
I am huge Ryoko fan. I did not enjoy the fact that the producers threw in a "fiancee" into the mix especially when it feels like a lot of the fans of the other girls where cheated on by this decision. Most of the first 5 episodes have to do with us getting to know Noike and an overzealous brother of Mihoshi (this is pretty much the only romance we truly get to see panned out in the OVA). There isn't much of a point in this OVA to me. Except to shake things up and explain a little bit about the Great Goddesses.
The only thing that saved this series for me was the very ending of the 5th episode and the entirety of the 6th. As as true fan of the original OVA, getting to see the Goddesses in full force was a great treat. Also, getting to know more about them was beyond belief. If I was to recommend this part of Tenchi to a new fan, I would only send them to the end of the episodes I enjoyed and explained to them what happens in the other episodes so they just get to see only the great in Tenchi. Over all, I didn't like the series as much. The final episode was the best part about it.
