I don't usually read autobiographies of any sort - if I did I'd have probably enjoyed this spoof even more, but it's a strong comic novel in it's own right.
This is a one-joke novel, but the joke itself has enough complexity to sustain the plot - Cheeta at the end of his career is looking back knowingly on his innocent beginnings, always enthralled by humanity, and the more he is exploited, the more he loves us. It's the perfect frame for a series of stories about Weismuller, David Niven, Maureen O'Sullivan and the rest of the set. The No Reel Apes campaign to end use of live apes in cinema is name-dropped from time to time although Cheeta himself is scathing. "That's what CGI is, Don, just men in suits."
