If there's one good thing that can be said about this movie it's that at least Kyla Pratt is dedicated to the character of Maya Dolittle. She debuted as the nerdy animal girl in the first Dr. Dolittle film when she was 12 years old, and ten years later here she still is, playing the character. That is dedication to your craft, and I can respect that.
That being said, this is an awful film. Pratt is actually one of the better actors in this whole lackluster borefest and even she isn't great, merely slightly above average. Though I mostly blame poor writing. None of the jokes are funny, the conflict is laughably out there - and not in a good way - most of the characters have no motivations, backstories or even characteristics. All the animals especially are just bad, being either stereotypical, rude, full of lowbrow humour or all of those at once.
The plot is one of those B-movie comedy plots mainly written to give room for all those wacky characters to spout wacky dialogue and to get into wacky situations. But, as already established, both the dialogues as well as the characters are poorly written and the plot itself is the poorest of them all. One of those three can be poor, and the two might be able to pick up the slack, so you can only imagine what happens when they all fail.
Still, there's really nothing actively harmful in this film. You can see that at least some of the actors believe in their roles and it has a good, if a bit clichéd, message it tries to convey. I guess that if you honestly have nothing else to do, this will pass the time, but I wouldn't recommend it. Kyla Pratt sure is cute, though.
