TNG: Encounter at Farpoint: Parts 1 & 2, streamed on Netflix.
I didn't think much of this in 1987, and not much more over a few other viewings since then, but have grown to appreciate it as of late. Patrick Stewart and John de Lancie were great right from the start, most of the rest of the cast needed a season or two (or three) to figure it out.
Oh, and of course De Kelley's scene made me smile, and cry, and smile some more.
It's funny, because I loved Encounter at Farpoint right from the getgo. I would have liked it even as a stand alone TV movie. It's still one of my favorite Star Trek moments, watching that premier in early October 1987.
