This is a case where I honestly think passing the Bedchel test would make the show worse, because it would essentially be putting unnecessary filler in what is already a way too short season.

And the second episode was loaded with extremely fun and exciting moments, and the puzzle was interesting and they solved it in a believable way. The interaction between John and Sherlock was amazing. So yeah, maybe the writers could have made the bad guys French instead of Chinese, and not occurred the wrath, but I don't have a problem with it being Chinese. It's still a good story.
