The 2D animation looks great in this film, and it pairs well with the grotesque nature of the story and it's hyperviolent contents, but then there's this awful... AWFUL 3D animation to represent the present day, and it's so, so, so, so, bad. Just an eyesore. I don't know who's idea that is, or what kind of budget constraints may have forced the team's hand, but the results are terrible to look at.
