Sci-fi/fantasy show recommendations?

I watch way too much British TV. I have just realized this. Well, I'll start with the British shows:

1. Doctor Who (sci-fi). It's Torchwood's great-granddaddy, and is much better in a lot of ways.

2. Demons (sci-fi/fantasy). Pretty good, if a little corny at times, but that's more than made up for by the very hot male lead.

3. Being Human (fantasy). A ghost, a werewolf, and a vampire all living together. 'Nuff said.

4. Life On Mars (drama). A DCI in Manchester gets hit by a car in 2007 and wakes up in 1973 and has to solve crimes. Also, it's got John Simm in it, and that's always lovely. Make sure you watch the original British version, though, because the US version is... well... crap.

5. Merlin (fantasy). It's about Merlin learning to be a wizard while he's a teenager. I've seen a couple of episodes and it's fairly amusing. I think this one is actually on ABC or something now.

You've already seen most of the decent American stuff, so I'll just go with the old standby: Star Trek. 100% classic. Both Classic and The Next Generation are awesome. Go with Classic if you prefer brightly-colored, cornier, womanizing starship captains, and TNG if you prefer the stoic, intellectual, stolid type. Or you could always go with both. That's what I do.

I think you should start watching Big Bang Theory and Dark Angel. Those are the most amazing television series that I had ever seen.

Ghost Whisperer ? I like this show I am not sure if it is sci-fi/ fantasy like but it has to do with stuff like that.

Maybe the Show : Medium , it is very interesting.

I hope this helps:)
