The crew actually obeying the Prime Directive for once instead of ignoring it, even in the
face of opposition by the higher-ups.
The reestablishment of the Riker/Troi relationship.
The in jokes, nice for us Trekkers, but incomprehensible to those who haven't been watching
the show all along.
The bad points:
Characters being out of character. I mean Data shooting at people and taking them hostage,
Picard and Worf singing and dancing, I mean come on really!
You would think that if the planet was supposed to be a fountain of youth, that Picard would
at least grow back a little hair to make himself even more attractive to his new girlfriend. I
mean almost everybody else showed signs of the aging process reversing itself, why not him?
