Let's face it; people are drones. They flock to see anything that's heavilly hyped, with endless Burger King and other merchandising tie-ins. Suppose Wild Wild West had no publicity other than standard newspaper ads, movie theater trailers, and a few rarely-aired TV spots, and South Park: Bigger, Longer and Uncut had a bombardment of publicity, it is probable that Wild, Wild West might have barely broken even at the box offfice, while SP:BL&U would be a smash, continuing to play in packed theaters six months after its release.
Box office smashes I have never seen: Independence Day Titanic Wild Wild West Star Wars: Episode 1: The Phantom Menace
I think the public is kind of stupid. I thought Eddie Murphy's "The Distinguished Gentleman" (a box office flop) was a much funnier movie than "The Nutty Professor" (a box office smash).
