This seems to be the case with more than a bit of what is sometimes presented as "outsider" art. Of which this seems to be a classic example. And why shouldn't a pervy homeless stalker with a homemade camera get a gallery showing? Makes as much sense as anything else. The thing I like about this sort of art is that unlike a lot of "real" contemporary art, when it works it's like getting a glimpse right into the inside of someone else's head, in a direct, unedited way. Which can be disturbing and weird, because it works against the conscious control we normally try to exhibit in our daily lives.
So yeah, he's a pervy homeless stalker, but the pictures are still cool.
Yeah, I think that's a pretty good analysis. Sometimes it works, sometimes it doesn't. I'd like to see it in person and see if my perception is different.
