This. So much this.
I'm on the record saying I was disappointed they chose Bullseye when I thought there were more compelling villains they could have chosen. (Though I also understand why they chose him, given his, in my opinion largely undeserved status from the comics.) Some of that was alleviated when Typhoid Mary popped up in Iron Fist, as she was my first choice for the next villain. But I was hopeful that the writers who have made Fisk such a compelling figure could do something with Bullseye to make him worth watching.
And they delivered. In spades. This character has been a blast to watch. He's the anti-Matt. One, a good man pulled towards dark actions. The other a complete sociopath who has spent his whole life trying to walk the straight and narrow. One a hero, the other a killer. And maybe both monsters. Sometimes it pays off to have faith in creators who put this much thought into a character, and I can honestly say now, in retrospect, that I'm really happy they chose to use Bullseye for this season. I have been proven wrong, and couldn't be having more fun.
