Here is the guide to viewing the three episodes:
Episode 1: WTF? But that was oddly good.
Episode 2: WTF? My god, was that awful!
Episode 3: Yes, this is exactly what Conan Doyle himself would have done today. It’s full of WIN!
But you can’t skip episode 2 because it’s necessary for character development.
I can’t wait for the next group of Sherlock!
