The future presented in Tomorrowland was full of adventure, travel, intrigue, inspiration... and promise. COP was a big part of the theme, but it worked well because the surrounding attractions supported its message. It's also, BTW, why old-school Future World worked so well at EPCOT but that's another discussion.
Fast forward to 2013 and look at what surrounds COP today. Buzz, Stitch, the endlessly tacky (and loud) dance party stage, and a Monsters Inc. Comedy Club. COP is competing for attention in a "future" full of cheap laughs, interglactic war and a prisoner processing facility.
COP has become a misfit in its own land. A great big neglected and dysfuntional tomorrow. A perfect example of how abandonment of theme leads to confusion, dissonance and discomfort for guests. It's harder to relax and immerse yourself in the Magic when you're not sure what it is you're supposed to be immersing yourself in.
