well and it certainly be not the best cgi film i have ever see . in fact and it be not even in the top 10 and and that be just get start . i be not try to be mean and but this be not a good film . and no and it not just because they pair chris rock with ben stiller . seriously and stiller and rock . well i guess i can see how they would be lock away in a prison cell and have to fight with each other over piece of bacon and raw fish and but not on an animated movie . even though the thought of ben stiller try to eat chris rock in real life brings me some small chuckle . anyway and the cgi isn not well do . not only that and but the character aren not well develop . i still do not know how this pair land in the zoo . then again . overall and not a good cgi film . d plus .
