I hated it, too. Of course, I also hated “The Forty Year Old Virgin”. I fell asleep during both of them rather than waste my time seeing how they ended. I got the impression that both films were written by teenagers who’d just discovered boobies.
Films I turned off/walked out on:
Platoon - too graphic for me
Blue Velvet - The twenty minutes I watched were enough to convince me that David Lynch was one step away from being a serial killer
Films I would have walked out on had I been older and wiser:
Eyes Wide Shut
Leaving Las Vegas
The Piano
