Just power-watched the first two seasons, I know, late to the party, but if you're even later than me, you really should dive in. Some fantastic work, though the violence and gore makes "The Walking Dead" look tame. But it's more about the characters and their very careful development.
Vincent D'Onofrio is doing simply amazing work here as the villain who becomes "Kingpin". The entire first season is devoted to Kingpin and DareDevil's origins, season two brings in The Punisher, done in a way the movies have never handled right.
