I hadnt ever seen this little animation from Dreamworks Animation until now, Madagascar is a fun ride with some serious animation polish. The rendering has some beautiful elements from things like hair and fur to effects of lighting and fire etc. The modelling has plenty of nice character to it with signature pieces like the angular feet/hands and those super spirally nostrils.
For me it is the penguins and indeed those kooky lemurs who make the film - they are great. Those penguins may even get their own show (see article on nydailynews) - indeed there is a sequel coming our way in Nov (Madagascar: The Crate Escape)
