The first episode of Penny Dreadful: City of Angels is available for free on the Tube of U. Natalie Dormer, from Game of Thrones, stars as a demon/goddess/witch who is up to no good in 1938 Los Angeles. She's pretty good at rousing up trouble. Brent Spiner, Data from Star Trek: The Next Generation, appears as a police captain (hey, he finally made captain!) in two scenes.
There are no BF/bondage scenes in here--at least not in this first episode. The series might produce a scene or two down the line, just like the original Penny Dreadful did, but I'm not bothering to get Showtime to find out.
This first episode left me feeling pretty "meh" overall. See it for yourself for free before they take it down.
