This is why half the movie plays out as a greatest-hits homage to the trick camera work of Danny Boyle, Godfrey Reggio, and Jonas Åkerlund (a useless shot of Ben falling onto a bed is a perfect example of how to squander an entire day of shooting; one ray-of-light shot accomplishes nothing but vertically flipping Koyaanisqatsi 's DVD cover art), while the rest occurs as tacky fits of juvenilia, the nadir of which is a bathroom-mirror montage of the story's motley characters getting ready for a party that ends with Ben's best bud whacking off to a nudie mag—his bottle of lotion opportunely evoking the man sploog exploding below the frame.
