Duncan was fine in the role, but he never really sold it for me. He seemed to be going for something of a version of Fisk with artistic license, which is fine, but I think the Netflix version did that aswell and captured a version much closer to the comics in the process. Pretty much every character except for Bullseye has been done better on the show, I think. Daredevil, Elektra, Foggy, Karen Page, Urich, and Westley, certainly. 

I'm curious to see if Season 3 brings in a better Bullseye than Farrell. Or at least a version that feels like Bullseye, because as over the top as Farrell was, he at least kinda fit the manic insanity of that character.
