Another review! This time it's Peter Bradshaw from the Guardian:

This debut novel from the award-winning screenwriter of movie masterpieces such as Being John Malkovich and Synecdoche, New York, is funny, exhausting and very, very long. Reading it is like watching (or being) someone trying to sprint to the top of an Escher staircase.

[...] Finally Antkind comes to its crazy, hellzapocalypticpoppin ending, and this twilight of the puppet-gods dwindles into darkness, leaving me with the punchdrunk feeling I have after all Kaufman’s movies. He may be someone for whom anxiety and sadness are a personal ordeal, but he transforms them into bleak, stark, unearthly monuments to comic despair. (Source)
