How did I miss this one

I just watched Wicker Park starring Josh Hartnett. It was made in 2004 so I imagine for some it's old news, but I personally hadn't heard of it until randomly coming across it during one of my dvd treasure hunts.

The intentionally vague description:
Noir, sex, time-lapse puzzle box, thriller, with always tantalizing Hartnett flesh.
(there be female flesh in there as well for all involved - but, dude, it's Hartnett, what can I say)
Oh, and it's a Must See.

( Spoiler alert under the cut )
