La la la (*covers eyes*)...I've just finished "Unity." I'm not reading the comments above.
But I will say I thought "Unity" was good and I'd love to see more like this. It would be neat if the Cooperative somehow turned into a new kind of Borg enemy, or if they became enemies of the Borg who come back in a later season in a surprise to help the VOY crew defeat the Borg in a critical episode. What I'd really like to see is the origin of the Borg. That would (potentially) be interesting.
I must have been in a funny mood early this morning when I watched the episode though. When Riley touched her face and asked Chakotay if he felt it, I immediately thought it would be funny if he touched his chest and said, "did you feel that?" Also when I watched "Blood Fever" I thought it would have been funny if the Doctor (a.k.a. the Pimp in this episode) -- when he went back to the holodeck, he found Vorik wearing nothing but a lei, sweating and smoking a cigarette saying "Doctor, you're a genius."
