To be fair,
@S 2 said "complete," not "full day." I think a lot of us are excited to see that area of the park finally get used in a full-blown way--I kind of view the Beastly Kingdom area as AK's Tomorrowland...not open on opening day, but part of the original package. Pandora fulfills the original promise of the AK concept, with the mythical dragon among the real animals on the entrance marquee. It should balance and fill out the AK experience in a way that Camp M-M never did. So in that sense, I would agree that Pandora makes AK a "complete" park, though, like you, I've always considered it a "full day" park.
