Interesting character, but way overused. To me she suffered from the "Data Effect" - I grew to despise watching both those characters. Towards the end of Voyager, I'd check the TV guide thingy to see what the new episode was about. If it was yet another variation on "Seven discovers her humanity" more often than not I'd do something more interesting - like wash my hair. Exactly the same thing I did in Data-centric episodes towards the end of TNG.
