I went to the opening of the Charles Burns expo yesterday evening. Very much worth your time. Check it out in the M museum in Leuven.
There has already been written so much about this dark and freaky comic, that I can't imagine I can add anything interesting to all that. The atmosephere is so specific, that I unconsciously keep thinking about it when I read other books or watch movies - like Meyer's Twilight or David Fincher's Zodiac for instance. Just google this one up.
