My Review
Glorious: one of the search terms that has led people to this blog in the past month is 'keep away from data bitch ontd_tng.' Dude, it has not been possible to keep me away from Data since approximately 1988. But let's press on with DS9.
This is one of those Star Trek standbys, an episode in which a core crew member gets possessed by an alien intelligence so that they can have conflicts with the rest of the core cast and/or generally act like a dick without it being morally their fault or breaking Gene's rule that We Don't Fight Amongst Ourselves or, in fact, having any impact on how anybody responds to them in subsequent episodes (this is particularly hilarious with Data; the most hostile anyone gets with him is when, after he goes berserk and stabs her in a lift, Counselor Troi presents him with a mocking cake). TOS and TNG would be such different shows if, after events like these, it took time for people to regain their trust in each other, and in some cases they never quite did.
Of course, as DS9 went on, it became apparent that you don't need anybody to be possessed by an alien intelligence for them to have some beefy conflicts and act like a dick (you have people like Dukat around who are more than happy to fill your dick quota), so they became less reliant on the old possession trick, or when they did use it did something interesting like introduce the Pah Wraiths. At least that's how I'm remembering it; I'll have to see whether that's borne out by this rewatch. I do remember that they did at least one other old-school possessionpisode, 'Dramatis Personae,' which I found striking because Avery Brooks played his possessed character with much more personality than he gave Sisko at the time.
For the second episode in succession, we'll get no O'Brien. I guess he's still in Japan, and I hope at least he gets to do some nice things like soak in a hot spring with snow monkeys. But hang on. Bear with us. Bullet point commentary again.
