Haven't read the books but after just 2 episodes want to do so. I like all of the casting and think the initial episode did a great job establishing the characters though at times I think Benedict is playing it a little too comedic. There's just enough tension and uncertainty to hook you. The premise isn't outrageous (variations on the theme having been portrayed multiple times in more "adult" programming / movies) and the cinematography does a good job of straddling what would appeal to multiple age groups. Worth your time!
