Seriously, can they make Charlie Kaufman’s enigmatic and surreal “Synecdoche, New York” anymore unappealing to mainstream audiences. Yes, we realize it’s going to be a niche film, but isn’t it a hard sell as it is? The marketing people are supposed to trick you into seeing it anyway possible, not driving you away from it. This is a real head-scratcher. Right now, it’s for the constituency and nooooobody else. Dumb, dumb, dumb.
