23. 'Buffy the Vampire Slayer' (1992 movie)
When Buffy the Vampire Slayer debuted on television in 1997, everyone wondered why the hell they made a show out of this weird, ultra-campy movie from 1992. These days, the film is more of a strange footnote in the Buffy canon – a rough draft for Whedon's infinitely superior and groundbreaking show. The movie has its charms, but Whedon's quirks were toned down considerably by Hollywood, and it's only worth seeing now if you're a Buffy and/or Luke Perry completist.
