Menage A Troi is gonna win this one. I voted for it
Also voted for:
The Hunted: Because it was one of a few heavy handed social commentary episodes in season 3, and possibly the weakest, IIRC.
The Bonding: Another fairly contrived one...the alien tech with the ability to recreate the orphaned boy's mother. Not sure what the point of the episode was...sort of a Worf vehicle...but not a memorable one. Shows the repercussions of families aboard ships, I suppose.
I almost voted EVOLUTION...for pretty much redoing the "UGLY BAG OF MOSTLY WATER" concept again. Data possessed. Ugh. Yeah, I should've voted it instead.
Also, I considered HOLLOW PURSUITS, because Barclay got tiresome in later years. Plus medical science should be able to cure him. Seriously, the amount of social disorders in the future should be nill.
Personally, I enjoyed the sort of tacky Melrose Place-ness of THE PRICE. In season 3, we see the Romulans and Ferengi as a recurring antagonists...with the Romulans being more liked, but here the Ferengi work. (thought they could've used both!). And yes, slutty Troi is more fun to watch than mentally messed up Troi ala THE SURVIVORS.
