The characters looked like dancing corpses to me. I always refer to Polar Express as the Christmas zombie movie.
I forget the term, but there is one for when computer generated models took so close to real, yet miss a few key details thus rendering them creepy and off putting. Aside from a few swooping camera shots, there is nothing I liked from Polar Express. Monster House on the other hand got closer to the mark. And that was supposed to be creepy.
Either way – Roger Rabbit should always be traditionally animated. That’s the foundation for the character’s appeal. However, a Judge Doom character could be motion captured. I just find the technology lazy when used for this type of entertainment. They should leave motion capture to video games for the most part.
I enjoyed reading the credits of Ratatouille where it states that no portion of the film was motion captured. It’s sad they even have to put that in. It is funny to think of a bunch of rodents running around with reference point balls stuck all over them, but the sad truth is that the entertainment community is filled with untalented people who try to slide by and fake it. In Zemekis’ case he’s a creative dude that has just given up in recent years.
