I'm big fan of supernatural (at-lest was as the start of the show kinda died down towards the end), constantine, carnival row. So you can obviously get the theme here. Will love some more suggestion in thous genre!
Penny Dreadful I've not seen listed but is certainly a great supernatural series. Not really supernatural but more fantasy/interestingly different. Into The Badlands. I know I'm forgetting some others but those are the first two to jump to mind.
You may also like Lucifer, The New Legends of Monkey, I Am Not Okay With This, and The Order. All on Netflix, at least in Canada...
V-Wars, Raising Dion, The Witcher, Locke & Key, The Kirlian Frequency are all good ones, too.
