Well, going a bit too far, yes? I don't think Disney execs are STUPID. I just think they made a bad decision. People can make bad decisions without being stupid.
If a classic, Timekeeper was a pretty darned new classic. I, for one, loved it, but I do enjoy MILFCC. The fact that the show is different each time means it doesn't lose as much on rerides. The technology is slick, and the humor, while uneven, seems to be getting better over time as the Monsters learn what makes hot tired tourists laugh. As for the placement, yes, it'd work better in Pixar Place, but the land has changed it's theme over the years. It is now really a Sci-Fi Fantasyland, so this works. Only CoP feels like the original tomorrowland theme.
Timekeeper did indeed suffer from poor signage and other problems, but don't forget, it has closed in Paris and Tokyo as well. Apparently, it just wasn't as popular as we think it should have been.
