Epcot: Journey into your Imagination as of today I think is the worse attraction in history, its cheap and nowhere near the good old Disney quality.
Magic Kingdom: I have to say Stiches great escape is pretty bad but I also wasn't very impressed with alien encounter either. I think that whole stadium with the effects it has is bad all together. I think they should switch out the well outdated effects on the stage and make a fear factor type experience, scare the living hell out of people and have a god thrill.
Animal Kindgom: I would have to say the whole street fair area just because I can see that anywhere and the sun beats down in that spot so bad.
Hollywood Studios:Now dont kill me for this this is just my opinion. I despise the tower of terror, the theme part is shorter than journey into your imagination, the line is way to freaking long and there isn't much drop time. Not to mention the fear of getting nailed by pennies and flying food which has happened. I can go to an average amusement park way closer and ride a more thrilling drop with more drop time, no line, and way more of a thrill.
