Single worst Borg bit. I mean come on. I know there's an in universe reason for it, BQ found him and kept around as an attraction for 7, but it just struck me as very hammy. And I love
I liked the Borg, I was never very keen on the Borg Queen's supposed fascination with Janeway and 7. Some of the Borg Queen's dealings with Janeway were very convoluted. However I still enjoyed the series being Borg heavy, great villain, always interesting (to me) if not completely coherent.
The 7 story arc itself is my favorite in all of Trek and of course you can't have that without Borg.
