I guess this is the pattern for all enjoyable animated films. What starts out as a viable stand-alone film (Kung Fu Panda, Happy Feet) quickly becomes a series of diminishing value only to bank on children’s interest and their parents’ wallets. The latest addition to this clause is Madagascar 3: Europe’s Most Wanted. Ben Stiller, Jada Pinkcett Smith, and Chris Rock return to voice the zoo animals in an attempt to return to New York. The film releases June 8, 2012.
