It's a strategy that's led me astray before, but at the Florida Film Festival a couple of years back, a sold-out screening of Hard Candy (okay, it would've been my second time) forced me to bumble instead into a showing starting right there and then of something Norwegian called The Bothersome Man.
Lo and behold, I actually very much enjoyed this deadpan tale of a man who finds himself dropped off in a banal purgatory of sorts, an Ikea-laced hell where money won't buy you happiness, drinks won't get you drunk, sex won't get you laid, and suicide won't get you killed. For the Netflix-savvy among you, it remains available on their Instant Watch format, and even on pesky ol' disc, I heartily recommend it.
Of course, I told you that to ask you this: What's the last time that you stumbled across a movie on pure and complete accident or convenience -- dragged on a date, came across on cable, etc. -- and with no recommendation that took you by total and utter surprise?
