I don't know. Maybe it's the new HD picture or something, but I actually found myself not really minding this episode so much anymore.
Yeah the "Okana charm" does get laid on a bit thick at the beginning, but eventually I found him pretty fun and likeable to watch. Plus, as someone said, it's the freakin Rocketeer!
As for the Data subplot, I thought Spiner actually managed to make that work, despite the iffy writing. And some of his lines (like the "jumping around like an idiot" one) actually cracked me up. I also liked Guinan's "Bring better jokes". And it was actually kind of heartbreaking at the end when he realizes the crowd's laughing isn't genuine.
In the end, it may just be a nothing fluff episode, but at least it's got a little bit of life
to it. Which is more than you can say for many TNG episodes.
