What is your favorite bad movie? (You know by most measures it’s not a very good movie, but you love it anyway…)

I entertain a number of contenders, but this is probably my #1:

The One (2001)

And my favorite part (aside from the thrillingly bombastic ending) is where the timestream cops flip through all the alternate universe versions of the main character and it is just Jet Li in a succession of terrible wigs. Genius. (Partly in the trailer in the beginning.)
