It's OK, the cast is good, they don't go The Tudors way, it's obvious there going to be some nudes (as in most Spanish movies, when I watch a French one I do expect to see someone smoking) but they try to do it by the book which is great, it's wonderful if you a bookworm who loves History as I am and you can tell they are doing it right, of course, some licenses should be taken out of a making this appealing to the audiences but that's fine, one thing I didn't like is that they chose to summon a lot of time within 17 episodes, that means some characters are introduced and killed or vanished within the same episode or two to say the most. This should have been scheduled as Isabel but I guess budged was an issue here, that was a pity, the whole thing felt rushed. Also, another concern here, Alfonso seems at the very end an old brother to his son Felipe (II of Spain) rather than his father, in those cases I guess is better to hire two actors, one young, one older for sometimes is puzzling to forget in spite of so much make up their real age. I'd advice anyone who loves history to watch this but If I have to choose, I will always go for Isabel instead of Carlos.
