Deconstruction of Falling Stars.
This was a filler episode for the series 4 finale of Babylon 5. It’s a little out of sorts with the rest of the series, but It is totally understandable as the 5th series was approved and the finale had to be pushed back to it’s natural ending.
A lot of people criticise this one, but I always felt that it reflected J.M.S’s faith that mankind, for all it’s flaws, would make it.
Maybe the episode, but Leonard Nimoy's acting was excellent.
Lost In Space abounded with badness, but I remember exactly when, as a kid, it stopped being science fiction and became just a sitcom like Gilligan's Island for me. It was the one with the Norse Gods. Odin hollers COME HERE! and Dr. Smith comes running, his legs spinning like a flintstepping cartoon character.
Specter of the Gun and Let This Be Your Last BattlefieldAll of those episodes of Star Trek TOS certainly qualify. There are others like The Corbomite Maneuver, A Piece of the Action, Patterns of Force, and most of Season 3.
And It's now going the Cinema feature route."Objects In Space", the last-shown episode of Firefly. For one thing it's got a very high "River is so mysterious and cool" count, which was always the weakest element of the series. For another it's got a really weird philosophical element (it seems to be about whether a thing becomes another thing if you give it a different name) which is absent from the rest of the show. It's not much worse than the rest of the show, but it's very strange and out of place.
I'd also nominate several episodes from the third season of The Mandalorian, especially the ones with the other Mandalorians. It feels as if once the show moved beyond its Wild West/Lone Wolf and Cub feel, the quality dropped off.
On the subject of Kolchak, the episode Demon in Lace . Very weak and muddled episode.The one with Frank Gorshin is pretty corny. I rewatched The Savage Curtain recently--it has some weak aspects.
The Youth Killer-- Kolchak the Night Stalker.
I think the idea is really poor just in concept--Helen of Troy as the monster?
I think they should have made it a Gorgon or Fury or something better.
There's a couple of other weak ones. Never cared for the one about the musical conductor being haunted by a ghost but the idea was better than TYK.
Some consider The Sentry the worst. I haven't watched it in many years but I didn't dislike it.
Quickly followed by the two with James Cordon.The Matt Lucas Dr Who episodes.
The most irritating character ever.
