I saw this with a friend last week. I found it an interesting little trifle, though I was quite surprised at the amount/level of acting talent that had signed up for such an oddball dark comedy.

One thing my friend confirmed, however: it is not uncommon for tourists in Europe to visit the grave of a famous author and read a chapter from the author's work while there; it's apparently considered to be a "sign of respect". Thus, the outermost "framing device" for this movie is actually based on an old and respected tradition...
