As of June, we'd seen it in Adventureland, The Haunting in Connecticut, Drag Me to Hell, Observe and Report, The Hangover, Year One, My Sister's Keeper, and I Love You, Man. Since that first post, I spotted 10 more: The International, Miss March, Thirst, District 9, Jennifer's Body, Zombieland, The Road, The Fourth Kind, Gentlemen Broncos, and Precious. That's 18 puke movies in one year. A new record?? I can only assume.
Why the excess of ralphing? The obvious answer would be that it's funny, and movies have lately been pushing new boundaries to get shock laughs. That's why we've been seeing more full-frontal male nudity, too. You used to get a laugh just by suggesting someone was barfing or naked; now you can get a bigger laugh by actually showing it.
Just something to think about while you are out on New Year's Eve . . . or tomorrow while you are recovering from it.
