They maintain it throughout the series. There are some really well shot fight sequences, long shots, multiple stunt guys, etc. One of the episodes pays homage to a scene from Oldboy (the original).
I think they nailed it in bringing it to TV. No sappy drama sub-plots like some other shows introduced (i.e. Arrow, Flash). I like the darker/grittier feel to the Daredevil series.
A couple of friends out west mentioned a 5 minute, no cut fight scene. Looking forward to it.
They did it right, without the "Peyton Place" elements, because it's not on CW
