I rewatched it the other night, too (or I had it on in the background while I was doing something else.) I was disappointed by part 2 at the time. I wanted a longer story arc at least. (sacrificing a lesser season 3 episode like, say THE LOSS, would be no loss!).
Okay, how did Picard overcome the Borg on his own?
Also, the Borg were distracted by the saucer section's anti-matter spread and the Enterprise's attack long enough for Data and Worf to get onboard and get Picard...yet, before that the Borg cube effortlessly took out some 39 Starfleet ship without appearing to suffer so much as a scratch?
Why were their no life signs at Wolf 359? The borg were on a direct mission and wouldn't waste time to eliminate survivors on life pods. In DS9's premiere we learn there were survivors (and later we learn there were assimilated humans from the battle..somehow). So where did those survivors go? Was this retcon abuse by later Trek or what?
We don't see any fallout from the losses at Wolf 359 until Redemption part 2. Surely, the more hostile races would learn of the deficiency and take advantage of the Federation's diminished defenses (of course in DS9, there were a whooooole lot of ships in Starfleet, so...), but this is something we don't see. It could've been mentioned in THE WOUNDED as a reason for Cardassian remilitarization. So it might be implied.
Did Guinan know that the Enterprise would survive, as well as Picard? After all her "echo" hadn't met Jean Luc in the Nexus yet.
Couldn't Worf and Data also have beamed over an old school bomb inside the borg cube as they rescued Picard? Maybe with techno-babble dampening field to avoid borg sensor detection? (Though if the Borg were concerned about sabotage they could've beamed the Enterprise's away teams into space, couldn't they?)
Isn't awfully convenient that Picard's assimilation didn't involve amputations and eyeball replacements?
