The Starlost, Episode 1, Voyage of Discovery (1973)
Summary: This episode opens the series. Three stilted young people from the dome Cypress Corners, as wood as their home implied, discover that their home is actually part of an ark in space, a colony ship headed towards doom.
Synopsys: Our lead character wants to marry Rachel, but is denied by the Creator, whose voice is heard from a black device. It turns out that the zelot leader of these space-quakers is using his own voice to speak as the Creator, that Rachel must marry the town smith. There's nothing wrong with the marriage at all. When our hero is chased by a mob of his fellows, he flees into the tunnels of the ship where he discovers the truth about his home. The ship will soon crash into a G-type star. On returning, he grabs his girl and escapes with her back into the ship, this time chased by the smith. When they discover the bridge together, the truth becomes self-apparent.
The show itself contained none of the pacing or humor that rival American shows had been showing, following instead the dryer pacing of early 70's British programming, such as Doctor Who. (If you doubt me, go watch the contemporary Doctor Who series "The Ark in Space.") However, as Doctor Who usually had colorful characters in the lead, this show didn't. I am honestly stunned by blandness of the main characters, who work to show little to no emotion at all. If there was any cast more lacking in chemistry, I want a showdown. Let see who lacks the most.
