Personally, I can suspend disbelief and really enjoy a movie like The Day After Tomorrow, but if you're one of those poor souls who is tormented by the implausible-- the Insultingly Stupid Movie Physics rating system is for you. In their system, The Day After Tomorrow was rated RP for "retch". Apparently it was saved from an XP rating ("Obviously physics from an unknown universe") for being guilty more of exaggeration than total nonsense.
