Bored right now, so just wondering which of these shows I should watch. Also if you haven't seen any of these then just skip this pick and move onto the next one..
:)

This is like the most in your face, well acted, scifi show you will ever see.

those all suck

This one. It gets better with every new season (it started the 3° season two Mondays ago). Word.

I haven't seen the others ones but SATC is one of the best shows I've ever watched. I've read BSG is really good too ;)

It really depends on your taste in shows. I haven't seen Battlestar but I have a couple of friends that swear that Battlestar was the most well written and genius sci-fi show ever. But I don't know if that's true since I haven't seen it.
I watched a few episodes of Xena many years ago when there were still new episodes... it entertained me when I was bored but I was never a fan of the show.

Sex and the City is one of my favorite tv shows. I think it's such a comical show and I'm a sucker for strong female friendships (and this show has some of the best friendships!). But you have to really like female camaraderie, fashion, humorous relationships, and comical dialogue to like Sex and the City. It's a COMPLETELY different type of show than Battlestar Galactica and Xena (I haven't seen Nurse Jackie and don't know anything about it)

It's a really fun show. I recommend it.

You won't regret this :)
