Kirstie Allie, Kirsten Dunst, Ellen Barkin, Denise Richards, Brittany Murphy, Allison Janney, and Amy Adams all don Fargo-esque Minnesota accents and dive heels first into the inanity. The film may have been ignored at first, but it's become a quotable classic in the past 15 years. It's really the combination of the accents and the dialog. Some things are just funnier that way, dontcha know.
It's done mockumentary style, so you get a lot of insights (for better or worse) into the character's twisted and special psyches. We meet the pageant runners and the contestants. Find out why they're involved, what they're planning for the show, etc. Then one by one, the contestants start dying from mysterious and suspicious causes. Things get \m/ up and hilarious. Offending everyone possible but leaving you laughing so hard it doesn't matter. Love it.
