No. It is about the experience of walking past the tile artwork. It is about the experience of transitioning from the outside to the inside of this expansive space with its specific decoration. It is about the experience of walking down into the roots of the building to see what it has to offer.The experience of poor crowd flow?
You challenge the way they have you enter The Land, but not Seabase Alpha? Maybe it is just that one appeals to your personal interests and the other does not. They both send you on a journey to get from the outside to the attractions rather than giving you a straight hallway. That's the difference between what Epcot was originally, a set of themed pavilions, and what you seem to expect, a bunch of buildings with rides and shows.Imagination and Seabase Alpha both went in the other direction.
