I am by no means a fan of motion capture. But I think that's because Zermerkis had a crappy system. This one looks far more full of life and vigor with GOOD character designs than any of his films did. Why he felt the need to make Polar Express look so whispy and zombie like was beyond me. But this system used here looks quite good. I still prefer entirely CGI animation that doesn't use MoCap, but this time they managed to make it look good.
