Well, I liked Wild Asia. Parts of it (start and tigers) are really the only places in Bronx Zoo where I felt they replicated my past experiences in the wild. Like jeep ride in dry forest in Ranthambore or some other reserve in central India.
I didn't like that all exhibits were passed at about the same speed. With tigers, elephants and interesting behaviors it was too short. When we passed tigers, the guide had even to hurry that all visitors see the tiger. (BTW, laser pointer would help there, like ones used by birdwatching tours).
I didn't like that commentary was rather bland and impersonal. No wonder visitors looked bored and the train had to go fast. "A deer, it is endangered, another deer, it is endangered, another deer, it is endangered". I think it was meant that visitors see replica of some generalized wild species in wild nature, but they overdone it. I would tell more about individual animals, some trivia like their names and likes, dislikes, about specific reserves and conservation projects. It is personality of animals and small details who engage people's mind.
And I would like baiting animals to the front. Perhaps also children given apple each, to throw to their favorite animal.
BTW - in India, even resting deer were interesting. You could see the herd structure, enjoy some small interactions between animals. I don't know why in zoo it was boring.
