A slightly unnecessary but touching sequel. Persepolis 2 is good and a must-read if you enjoyed the first Persepolis. But there is just something missing in the sequel. The story is unpleasantly disjointed in parts and the pages aren't very visually interesting, which is pretty problematic in a graphic novel. I don't know much about the historical accuracy etc. of this novel, as I am often wary of memoirs written for western audiences because editors have exploitative tendencies but I can say that this is certainly an enjoyable read.
The first Persepolis is an absolutely stellar graphic novel. I consider it definitive of the genre. Persepolis 2 is merely good.
