First of all, I think the story on Cathars is a brilliant topic for film - barely touched in films. I'm disappointed that not everything was filmed in location (Southern Africa? Why? Languedoc and around wasn't good enough?). The other thing, but it's a personal thing, the archaeological excavations were rubbish - nobody digs like that! (but I'm an archaeologist, so it's my thing). I didn't really enjoy the modern part of the story because of acting - actors and actresses were very stiff and unnatural. It looks like the modern story was directed and filmed by somebody else, but the Medieval part was much better in execution. I give 9 for the Medieval part and 3 for modern part, so it's 6 in general. My opinion is based on the first episode.
