Great sets, plenty of side plots that satisfyingly converge at the end, and good acting.
The tone and presentation of this show surprised me greatly.
I admit that before this I found Cara Delevingne's acting stale and boorish, but it seems that she has finally come into her character acting. Hers and most all the characters are interesting and well played.
If you're looking for a new intriguing noir fantasy or are just a fan of well made shows, then Carnival Row is more than worth a try!
