One thing I didn't like. SPOILER for the first Insidious Six episode.
There were all these other crime bosses telling Kingpin what to do in that episode. That's stupid. In the comics none of the other crimebosses even tried to mess with Kingpin cause they knew Kingpin would try to kill them if they did. Except for when his son created a secret identity to try and overthrow him.
