Time Out says
So, when Glickenstein accidentally expires, Igor sets out to prove his worth by inventing the most monstrous of all monsters in Eva. However, Eva turns out to be more caring and thoughtful than destructive, and eventually persuades Igor that more comes out of being good than being bad. The animation here is vaguely Tim Burton-esque with a nod to Ralph Steadman in some of the outlandish characters, especially that of Eddie Izzard’s key villain, Dr Schadenfreude. But there’s not much form to the plot which develops in fits and starts. Nevertheless, those kids that weren’t confused appeared to enjoy it, so there you go.
