Let's be honest here. I love great Imagineering concept art for the Disney parks as much as the next guy, but it's become all too common for the suits to rush through quick and dirty projects into being- and the resulting concept art can be just as ugly.
Animal Kingdom's striking blemish of a land, Dinorama, comes to mind. (I don't care how Joe Rohde tries to convince us its such a good design fit for an otherwise gorgeous park.) So does just about anything from California Adventure at opening. (Even that art for Twilight Zone Tower of Terror shows a kid facing the camera that looks like he's cursing it or saying "What the Heck is this?") The winner in ugly art, however, has to be Walt Disney Studios Paris. Hands down the ugliest of all Disney branded parks past or present. It is very telling that you don't see this kind of crap at Tokyo Disney Sea.
The concept piece above shows off the billboard like entrances for attractions passing themselves off for good design. Imagine paying full price for a park that looks like this. Yet, we do.
I am so thankful that Universal Orlando upped the stakes by adding Harry Potter and the Forbidden Journey. Otherwise, we'd still be getting garbage like this stateside.
