I very much enjoyed Thomson's graphic novel
Blankets, but was aware that Habibi came with substantial warnings about cultural appropriation: it's a love story of two kids trying to escape and build a life of their own in a fictional Middle Eastern country, which is half Arabian Nights fantasy and half modern oil metropolis. It's beautifully drawn and the central characters (including the wonderful Noah the Fisherman) very well portrayed; and the whole thing draws deeply from the wells of Arabic (and also Persian) lore and culture.
It does have some serious problems. Nadim Damluji discusses his issues with the depiction of Arab men
here and takes it up with Thompson
here; like him I also don't quite see where Habibi is in dialogue with Orientalism rather than simply performing it. (I thought the farting dwarf was well over the top, too.) Also there is some very nasty sexual assault in the book, and even though it is not depicted graphically on the page there is a serious squick factor which readers should be warned about.
Thompson wanted to do some imaginative cultural exploration in the aftermath of 9/11, and has certainly done so, though I'm not sure it went quite in the direction intended. But that happens to all of us, really.
