This is an interesting and tense story, but I do have a few issus with it. First is the inclusion of Madam Vastra; unlike the first few cameos she isn't a reference to an older story but simply a character who happens to be here now, much like the UNIT people. With every episode having someone this is becoming increasingly fanserving and unbelievable. At least the UNIT people had the actors to help pull it off, but nothing with this Vastra feels like the original.

My second issue is the music. The sound design seems to have taken a dive, and the music is incredibly loud and distracting, and doesn't fit the scenes it's overlayed on.

Honestly, while there isn't anything egregiously wrong with each individual episode of this series, I just can't wait to be done with the series as a whole.
