I invariably get misty eyed during the conclusion of The American Adventure; Nice to know I'm not alone. The real point, though, is that we need more attractions like this. The nostalgia which Walt Disney World lives on today was formed through an emotional attachment, as opposed to how fast the ride spins or drops or even application of the latest 'hot' IP.
Given a choice between something which entertains primarily through physical thrills (the tallest, fastest coasters, etc.) or an attraction which forges an emotional connection, the thrilling ride simply can't hold a candle. Whether the tear inducing American Adventure, the inspiration of Horizons, adoration for the original Journey into Imagination, or the spectacle of Spaceship Earth these are the experiences which once defined both Epcot Center and a pinnacle of Disney creativity.
IP based attractions are certainly popular and far more marketable, but do they speak to our emotions in any similar manner?
