The animators who did the “Ice Age” series and “Rio” have tried to go classy with this fantasy about a miniature kingdom of plants, animals and creatures in a battle for the beauty of nature. A young human woman gets involved in their world. The plot drags it down. It’s too complicated & too talky. The art direction is sometimes attractive, but some of it is weird. The snappy humor and wacky characters that make their other movies such fun is almost non-existent (only Chris O’Dowd and Aziz Ansari provide any laffs). The whole thing is adequaate, but not much more.
