ST:TNG may have had my favorite series ending ever. It tied in beautifully with the series opening, and felt like it was an organic culmination of the series as a whole, rather than something tacked on or an arbitrary ending. It also gave us lots of tantalizing glimpses of a possible future that we would never see, leaving us to wonder, "How much of that would ever really happen?"

Plus it had Q. Everything's better with Q.

I remember turning to my friends afterwards, deeply satisfied, and saying, "If it had to end, I'm glad it ended that way."
