10. THE AVENGERS "BIZZARE"

Steed and Ms King go off into space in a rocket. No, really. 

9.  TWIN PEAKS

It's not often you watch a television show in which the bad guy wins. Killer BOB gets his claws into Cooper, to be honest, a rather frightening conclusion.

8. FARSCAPE "PEACEKEEPER WARS"

The miniseries finale, provides a solid conclusion to the series, even if some characters were brought up short, well it is Chrichton's story after all..

7. DEEP SPACE NINE "WHAT WE LEAVE BEHIND"

The resolution of the Dominion war, plus a couple of moving swansongs from some of the characters.

6. STAR TREK: THE NEXT GENERATION "ALL GOOD THINGS.."

In which Picard journeys back and forth between an alternate past and and alternate future.

5. QUANTUM LEAP "MIRROR IMAGE"

Does Sam Beckett ever get home? No. And it's rather sad, too. Turns out he'll carry on "leaping" forever.

4.  THE PRISONER "FALLOUT"

One of the most expensive pieces of TV ever filmed, "Fall Out" was The Prisoner's finest hour. The outrage caused by the unmasking of Number One caused McGoohan to flee Britain for good.

3. BLAKES 7 "BLAKE"

In which Blake returns as battle-scarred bounty hunter and the entire cast, apart from a smirking Avon, are killed off (well, maybe).

2. SAPPHIRE AND STEEL "ADVENTURE SIX"

A masterpiece of tension and intrigue. Sapphire and Steel are lured into a trap, ending up imprisoned for eternity in an empty void. Decidely odd, but chilling.

1. BABYLON 5 "SLEEPING IN THE NIGHT"

Set in the year 2281, the old crew come together in their new roles to pay respect to the dying Sheriden & the scrapped station.
