Once Upon A Time - The setup is that a bunch of fairy tale characters (Snow White, etc.) trapped in our world by a curse. It has some similarities to the comic series Fable, but only very limited ones. I'm only two episodes in, but this is very slick, sets up a good arc plot, and flashes back and forth between the fairytale world and our world nicely.
Both of them are worth checking out. Lost Girl is showing on SyFy, Once Upon A Time is coming to Channel 5 later this year.
Oh, and both are female-led, if that helps :->
