I, Borg is the recurrent Star Trek story which began with The Corbomite Manoeuvre - we treat our enemies in line with our morality, even though they have/would attack us given the chance. It's the concept of being who we say we are, even when it's hard, or disadvantages us. To me, those episode types are the essence of Trek. Insurrection was a rubbish movie, but it was a similar story - we don't cast aside our morality when it becomes inconvenient.At any rate, I think the 'I, Borg' choice is a fascinating moral conundrum, perfectly presented and played out, although I still disagree with Picard's decision. I do like that he has to answer for it later to Admiral Nechayev in 'Descent'.

- I entirely agree with @Spot261 on Voyager's wasted potential. It made me so annoyed that it wasn't what it could have been - this is why I find I dislike Voyager more than ENT even though ENT was just as bland and boring - Voyager felt like it was constantly squandering a really interesting premise to be TNG Mk II.
My other big thing to get out there - I thought Crusher and Troi were both rubbish characters and largely unneeded. They were never well written and Gates wasn't a strong actor. I would have preferred some females in other roles in the cast and ditch all three of the initial female roles. Marina Sirtis would have been a good first officer, or engineer maybe. Ensign Ro was a breath of fresh air in that department, a female character who was interesting, well written and could act. It's a shame she didn't pop up more often.
