I also forgot to say Extra Terrorestrial Alien Encounter at Walt Disney World. Replaced with a ridiculous Stitch's Great Escape! Which is a large pile of Vomit. It uses many of the same effects as Alien Encounter, but doesn't compare to it at all in my opinion. Alien Encounter is the only time that I have ever been truly scared on a ride.
It closed down because parents complained about it being too scary for their children, even though there were many warning signs and a height restriction. If it's too scary, don't let your bloody kids go on it!
Stupid Disney, being child friendly. We need thrills damn it!
