pre-thanksgiving pi

I watched Pi yesterday. It's by the same guy who made Requiem for a Dream and the filming is similarly dizzying, although Pi is in grainy black and white. The human themes are also the same: obsession, life spinning out of control, patterns of behavior, etc. I had a positive reaction to Requiem, but Pi...at the end I didn't feel like I'd gained anything, any perspective, any deeper appreciation of math or universal patterns. Was it just me?
