TV shows that need to come back

[Holst]

This follows the shows that gotta go thread, what do we need to bring back to make TV worth bothering with.

I nominate

Firefly...cancelled just before it became a hit on DVD and a movie.

Secret Agent/Dangerman/The Prisoner... there have been something like four different series already, how about number five.

Red Dwarf....the killed off Lister for the umpteenth time, so what happens next other than long standing movie rumours.

I'm sure I can come up with more, how about you.
