Picked up "The Gathering" dvd yesterday for 50 cents. It was the "Warner TV Premier DVD" 2004 version that came in a flimsy cardboard slip.
(Found it in the bargain bin at a discount store).
It seems almost like a standalone episode.
Well you have to remember that "The Gathering" was meant as a pilot, and was aired in January 1993, while the rest of Season 1 didn't start to air till September 1994. So it was designed as a made-for-TV movie of the week.
Plus the "Gathering", to date, is the only episode/movie to be presented in its original 4:3 format.
