I absolutely love this show.
It is very,very gritty. I just mentioned it on OT.
SGU had nothing on steamy scenes, the older brother is gorgeous evil naughty fun. Jeremy Irons is superb in it. The best thing about this is the character's are all three dimensional. And Heck you even find yourself feeling sorry for the assassin, if not respecting him. There is alot of drama to it. So, If you don't like drama, you might not like it. But it is historical drama. About the faliings of years gone by religious corruption to the papacy. A perfect example of why there is separation of church and state.
Murder, War, Sex, Politics....juicy
If I had to describe the experience of watching this show I would say devilishly delicious.
