Saw the first episodes and found it being a little slow in pace
Never saw Red Dwarf, but the appearance of the characters are a bit too caricate to me and reading about the series the humor doesn't sounds the type I normally like
The problem in seeing series with my parents is if they don't like the series from the beginning, forget. But maybe one day I give HIghlander a new try, even if I decide to see alone. And will check Blake 7
Gydion: AMC's Humans. Nothing groundbreaking, but good robot sci-fi.
Don't known this one, will check
Avogadro6: Tried X-files?
Only saw some isolated episodes
Telika: You could also check Torchwood. It's like... dr who done wrong, that is with added sex and violence to try to look more mature, and ending up looking less mature*. It's still watchable, and increasingly so as the series progresses.
Saw the first 2 or 3 episodes, my parents didn't liked because is more serious than Dr. Who
