Davinci's Demons is the dogs bollocks. I mentioned it on one of first (poss first) thread, but nobody mentioned having seen it.
We've got sky here though so I'm bit sure what channel it was on ie terrestrial or not.
It is awwwwwesome though. There is a Milady type character who is fiiiiit, a baddie Richelieu type character who is not obviously fit, but would make you want to do dirty things for him as per Cardinal.
There are sidekicks and can be v funny. It has sex, mystery, fighting, amazing Da Vinci inventions/discoveries, leather, lots of leather actually. Facial hair, dirty, grimey, sweaty bodies and lots of billowy shirts. There are several lead characters to fancy.
I highly recommend, but think it might be harder to find. Not seen it on Netflix, not sure if it was a Sky production etc.
