Bolt: The problem with a 3D cartoon

So I admit it - I went to see Bolt based on fairly positive reviews and its availability in 3D. There's just one problem - Bolt is an old-fashioned type animated film with flat drawings. Transferring those drawings into 3D only works so well - the grass, animal fur and other little details are amazing but everything else is still pretty darn flat. So after an hour and a half, I had a headache from the 3D glasses, was overdosed on cute puppies and truly enjoyed exactly two sequences involving east coast-west coast pigeons with very realistic head movements. I should have gone with my instincts and gone to see Madagascar 2 instead - I hear they have very entertaining penguins and monkeys.
