I'm not sure I "love" Voyager - though since I finally am spending the money for the DVDs (I resisted until they came down in price as they recently have) I'm still taking the series as a whole in (before now I've only caught probably half or so of it on TV airings). But I definitely enjoy it - the proper word is charmed I think.
The elements I most enjoy about it:
1. The central performance of Kate Mulgrew. The character was complex, and sometimes the writing was erratic (Janeway would be...at times...whatever the story demanded of her), but the fact is...Kate Mulgrew and the Janeway character anchor the story solidly...and she never overacted in the way Avery Brooks did from time to time. Her performance was solid, and her character deserves her due in the pantheon of Trek captains (I've been disappointed at her relatively minor role in the TNG relaunch...she could be put to better use than as a nagging admiral).
2. The cast in general. A strong cast and good characters. Even Neelix...a brunt of complaint for many Voyager haters...was solidly portrayed, with Ethan Philip's performance never as annoying - IMO - as some detractors have claimed. In fact...he charmed me from the moment in Caretaker when he addressed Tuvok as Lt. Vulcan.
3. While it is true that the overall Voyager arc - or lack of one - is disappointing, the fact is that Voyager produced a number of outstanding episodes that stand as some of Trek's best. Caretaker is...IMO...Trek's best pilot, and there are any number of great entries (Deadlock, Year Of Hell, Scorpion, Unity, Faces, Timeless, Death Wish, Living Witness, etc) that stand alongside Trek's best episodes.
Put a little more simply and clearly...I think Voyager gets a bad rap, so to speak. While it did have it's weaknesses, I watch it as Trek alongside TNG and DS9 with no problem. The same spirit of Gene Roddenberry's original can still be found in it...and it produced some fantastic hours of television.
