1. It was a box office bomb loathed by critics
Hitting theaters on July 27, 2001, Wet Hot American Summer opened in only 12 theaters, pulling in a paltry $295,000. Cowriter and director David Wain called the film a "financial disaster." But arguably worse were reviews that Wain's cowriter Michael Showalter describes to Time Out New York as "hostile." In his scathing review, Roger Ebert took a cue from the song "Hello Muddah, Hello Fadduh," writing: "Wow I hate it something fierce/Except the astrophysicist David Hyde Pierce."
