That's because it's absent of any street level activity on either side. Some restaurants and/or shops should have been put along that corridor to give it life.No but I’ve experienced WDW Tomorrowland and the land kinda feels dead walking into it. The Astro orbiters where Disneyland’s was and the people movers moving but when u first walk in it’s just feels like it’s lacking something.
EDIT: It also seriously lacks meaningful landscaping to soften it's look and give it a feeling of freshness. Too cold and sterile.
