The Frankenstein Chronicles S2
Overall a very good season, and a largely satisfying wrap up. The way they wrote out Vanessa Kirby between seasons is a bit shit, though.
Penny Dreadful S2 E1-4
I only saw about half of this season when it was first airing, but some iffy retconning aside, it's quite good and better than I'd remembered. Also, the bad guys are just Roald Dahl's witches, change my mind.
