I love
To the Death. It's not an episode full of big events, but we learned more about the Jem 'Hadar and their relationship to the Vorta, and it has some of my favorite dialogue from the show - Jadzia's conversation with one of the Jem 'Hadars (it was around that time that I started to realize that Jadzia, whom I considered a bit dull in the first couple of seasons, was actually awesome) and O'Brien's own version of the Jem 'Hadar pre-battle vow.
Retrospect, again is solid. There was always a lot of chemistry between Janeway and Chakotay, and they would have made a nice couple. It would have been wrong - the captain and first officer dating would be a bit unprofessional.
Personally, I find the whole "they are not allowed to date" thing rather silly. I find it very hard to believe that the Voyager crew would still be upholding every single Starfleet rule and regulation, even though they were so many light years from home, Starfleet and their worlds, and likely to remain in the Delta Quadrant for the rest of their lives. And if Janeway can't date any of her crew, who else is she going to date? Who is Chakotay going to date - he is the superior officer to everyone else on the ship? (Well, maybe not to Neelix...

) The only other options they had were holograms and casual affairs with random aliens (how fortunate that there were so many humanoid aliens in the Delta Quadrant, and that even the very non-humanoid had the habit of faking human shape... otherwise it might have been a little... awkward

).
And let's look at the only issue there really is about the captain dating the XO - that it might interfere with the way they fulfill their duties on the ship. For instance... if they got too close, maybe Chakotay wouldn't be able to provide a decent balance and check of captain's power, which would be especially important at times when the captain isn't acting rationally (say, in
Equinox)... maybe he would instead start caving in to Janeway all the time...
oh wait...
They were already "in bed" in every other way, what difference would it have made if they also started doing it literally?

If I were one of the crew of VOY, I'd be far more concerned that Chakotay had no balls to ever stand up to Janeway, than I'd be about them sleeping together.
Then again, if I were one of the VOY crew, I'd always be happy, satisfied, feel like a part of one big family, and would always support the captain in everything she does, because that's how I'd be written.
