We can all take some comfort that even Disney, with all its money and creative resources, can fail.
Take for instance, Disney's epic failure, a long-gone ride called Superstar Limo. The dark ride, that was once in California Adventure's Hollywood Pictures Backlot area, took guests in a sparkly purple limousine through a distorted version of Hollywood and Los Angeles. It was open just under a year and was later (and as you'll see in the video, hilariously) repurposed as the Monsters, Inc. ride.
Kevin Perjurer of the YouTube channel Defunctland describes it as their "worst attraction ever" and offers this critical history of it. His video is 20 minutes long but worth a watch, as his research goes deep and this "Superstar Limo" truly has to be seen to be believed. Be sure to stay to the end to see the reactions of the cast of The Drew Carey Show and Rosie O'Donnell when they all took a whirl in it together.
Also, in case you're curious, here's a look at the ride without commentary:
