I haven't read the book this series is based on, so I don't know how faithful it is to the text, but other reviewers advise that it is very faithful. Kudos to the producers if that is indeed the case. But even if it isn't, this is still a deliciously clever and funny and, yes, irreverent take on the events surrounding the Apocalypse. It is brilliantly scripted, cast and acted. It is hard to imagine how it could be better.
