Just finished watching the whole series, all I can say is, wow, my god, it was epic, and so organic in it's flow, nothing seemed forced or just there for the sake of being there, each and every character has incredible depth to them. I loved the two sides of the same coin analogy with Daredevil and Fisk. It doesn't shy on the grittiness at all, I mean this show is dark, oh boy is this show dark, but you still believe the characters can exist in the more PG-13 world of Marvel. I would love to see Daredevil make an appearance in an upcoming Marvel movie, Civil War comes to mind, or heck Spider-Man would be awesome too. Maybe a cameo in Agents Of Shield?
Bottom line, I loved this series, and can't wait for season 2 and the Defenders. Go watch it, like right now, go do it, you won't regret it one bit :thumbsup
