Thanks to John Frost at The Disney Blog for highlighting the blog entry at 2719 Hyperion on this now-famous phrase from Meet The Robinsons.
To me, this movie is almost like a love letter to Walt Disney. The salute to "Tomorrowland" being "Todayland", while very funny, certainly showed as a sign of affection. And of course, the very last frame of the movie, with this quote from Walt:
Around here, however, we don’t look backwards for very long. We keep moving forward, opening up new doors and doing new things… and curiosity keeps leading us down new paths.
... almost became the "running theme" of the whole movie. I've read so many people (Disney fans) online writing on how emotional it felt at this very end. For those of us who have fallen in love with Disney, this is highly understandable.
Whether it was intentional or not, Meet The Robinsons, to me, is a letter of love and affection to Walt Disney from the Walt Disney Company. And it was crafted via a wonderful movie.
