I think they wrapped it up beautifully

I just finished watching the third season (only saw the first season when it was on german television about 15 years ago), and I think they did every important character justice in the last episode. And the interview section with the cast at the end was very touching. It's really a shame that the show got canceled back then, and I never saw a show quite like this since, but at least they had the chance to wrap it up and write a good ending, even though they were still hoping for another season.
