Great news and much deserved. Enjoyed Daredevil, certainly a highlight point for Netflix in 2015, and would eat up more of it. The other upcoming series, Luke Cage etc, can only get us more pumped for them too. Considering they don't have to worry about normal tv stuff, I'd be very surprised, if any of them turned out bad.
One thing was also in the back of my mind, after watching Daredevil. That thought is that Netflix should really consider hitting up Marvel, for getting a Punisher series made in the same vein. Punisher is another street level hero, that's just crying out for a decent series, and has only been served so well via movies. (Warzone was cool, but the first one (with Dolph Lundgren) was, okayish/luke warm).
Anyway, keep going, Netflix. Now all you need, is your own Game of Thrones type adult fantasy series and everyone will be happy. Plenty of other good fantasy stuff there.
