This Week in TV is a weekly feature reviewing the best, worst and most interesting episodes of television from the past seven days. The plan is to cover a wide variety of shows, but not always the same ones each week, so let us know in the comments which ones you’d particularly like to read about. This week sees Penny Dreadful return for a second season of Eva Green-starring gothic lunacy, Sheldon and Leonard’s mothers paying the boys a visit in Big Bang Theory, and two departures in New Girl.
