I love this movie, and would really hate to see it go. I'll definitely agree that it is showing it's age, but its most memorable moments focus on landmarks and vistas that are arguably timeless. Mont St. Michel, the Alps, Notre Dame, all of these images are just as memorable and recognizable today as they were back in the 80's. The cinematography and score are beautifully, and the narration is pleasantly understated for a theme park film.
However....I get that this is just my opinion. I can't imagine many families are planning a trip to Epcot to watch this film. I just hope that they can find a way to add value to Epcot without having to gut yet another classic attraction.
