Mada'gasp'car

For someone who is an absolute sucker for animations, I was rather shocked and confused as to why I could'nt sit past the first half hour of Madagascar! I did'nt warm up to the characters and neither did I find them funny. With voices of Ben Stiller, David Schwimmer and Chris Rock - how could this happen? Am I growing too old for animations? or have I lost my sence of humour? Or is my mind simply making redundant any light hearted stimulations and forcing me to grow up? Hmm.
