How does it fare? Pretty damn well. Apart from updated animation and pop-culture references, it's pretty much the same programme. There are a couple of changes, like DM inhabiting a world of anthropomorphic animals rather than the human word, so he's living in a giant postbox rather than a normal-sized one; but I wonder if that was a choice to avoid confusing an audience that will be unfamiliar with the premise? That one, niggling, complaint aside, Danger Mouse is a fun ride from start to finish, with classic and new villains, flashbacks to episodes older than I am and more than one appearance of Count Duckula. The episode where the villain is a trivia-quoting DM fanboy is priceless, if a little insulting.
Although nerds are always quick to cry "reboot", as if it's a racial epithet, that's not what this is. Danger Mouse is not a new series, devoid of continuity, but is a new series after a long hiatus. Hopefully, a new generation of nerds will be asking their parents who Duckula is and they'll soon find their way to Avenger Penguins. What? Kids need to appreciate the classics, not all this angry birds and Bay turtles crap.
