Well I wasn't part of the discussion until now, so slow your roll, son.
Acting and writing.
Vincent D'Onofrio is amazingly compelling as a villain. Matt Murdock wants to preserve Hell Kitchen as he remembers it and keep the locals where he feels they belong. Wilson Fisk wants to revitalize the area, raising his home to a promience he feels the region deserves. Both men want what they believe is the best for Hell's Kitchen and in the wash, Fisk's ultimate end goal might actually be better for the neighborhood.
Fisk is a thug who wants to a businessman, but for whom the weapons of criminality work so well. A violent man, prone to fits of rage, due in part to the past rage of his father. Once again, parallels. The death of both fathers essentially created Fisk and Daredevil, but Fisk was the instrument of his father's death. It was a necessary act of self-defense, but it was still murder. His road to what he sees as herodom was tainted from the beginning.
Fisk is also horribly sympathetic. You can actually see that not only does he believe this is the best for Hell's Kitchen and everyone in it, but he is also a man that loves deeply. He craves it. Vanessa, his mother, even Wesley.
The best villains are the ones who you can see yourself in their shoes.
Wilson Fisk is an amazing villain.
