Everyone knows the genius of Rod Serling's science fiction, suspense series, THE TWILIGHT ZONE. NIGHT GALLERY was a different sort of series, bringing horror to the small screen. Stories by the likes of H.P. Lovecraft, Richard Matheson, and Robert Bloch were presented weekly, in a macabre art museum setting. Serling himself was the "curator" / host. Each episode was like a mini-feature film. There was great care and quality involved.
The reason this show never reached the same stellar status that TTZ did is easy to discern. While the first season is filled with many classic episodes featuring supernatural, sometimes surreal tales, studio meddling and economic pressures doomed the later seasons to a more conventional TV hell.
The network -obviously- was only concerned with better ratings / profit, so, it demanded shorter segments, more "accessible" stories, and, of course, comedy. Serling, being the eternal iconoclast, hated this nonsense, but had no real choice. If it had all been done his way, without the tampering, NIGHT GALLERY would have been a horror masterpiece. As it stands, it has the first season of brilliance, followed by a second decent season, and a third that is hit and miss. Still, this show was unique, and even its worst episodes were better than most of the rubbish on TV...
