Lost Girl is now up to episode four on SyFy.
If you liked Buffy and Angel, you'll probably like this. It's got that vampires-are-real kind of world mythology, with the more 'adult' themes (aka people don't just fancy those of a different gender from themselves, and sex happens) that Angel and later seasons of Buffy had.
But where Buffy dodged the bi bullet with Willow's instant gay/straight flip, Lost Girl takes the bull by the horns. Our central hero, Bo, is a succubus, feasting on the sexual energy of whomever comes to hand without regard for gender; and when faced with a choice of joining the 'light' or 'dark' supernatural sides, she walks the line between them instead, not feeling herself to be either one thing or the other, and thus faces bewilderment and opprobrium from either camp.
You know, I think there might be the odd hint of the Big Book Of Bi Cliche there.
The first season finished showing months ago in the USA so as it starts showing here, I hear of it getting renewed for a second season. Our two lead characters are both women, and programme commissioners on the other side of the Atlantic don't seem to like their scifi to have too many strong women in it: see the cancelling of Caprica or Firefly. Hopefully they'll continue not to notice that our hero in this one is a woman for another couple of years.
