Napoleon Dynamite.
Forever lost hours of my life.
That entire movie was filmed for about $400,000 and yet went on to gross $50,000,000. Not bad.
As for truly bad movie, I would go with "Pee Wee's Big Adventure". I was always repulsed by Pee Wee Herman (played by Paul Reuben), even before he was caught pleasuring himself in a movie theater. Just a creepy character all around.
Nawww! Napoleon Dynamite is one of my whole family’s favorites! We’ve seen it countless times.
