This is one of those odd films where screaming as bluntly as possible at the viewer actually works well for it.

Your dosing off slightly as the generic heroes/villians and annoying child character wash over your eyeballs becoming comfortable sleep is near and BANG!! The movie cuts to the bridge and howls like a demented banshee at you. The music and the lingering shots telling you THIS BRIDGE IS SO FUCKED!!

Any tea you might have in your hand will immediately shoot up into the air and you'll find yourself telling the film you were not falling asleep that was just you resting your eyes for a moment.

Simple yet effective.
