I'm re-reading this as part of this month's extra-curricular writing project (that's supposed to sound flip, not pretnetious. I hope it comes across that way). It's really good, if slightly uneven mix-- I like Keret, and I really like the Actus Tragicus folks. The winner here is Modan's "Romanian Circus," which I think might be closer to a collaboration than an adaptation, since I can't find an original prose version of the story. But this is really good, and read alongside the originals, there's a lot to like here.
