Just saw a new trailer for this, and it looks even worse than it did at first. Anyone who watches this based on the CG, either have no taste or will be extremely disappointed. It would have looked much better with real actors (it was perfect in 300, I don't know why they are changing from that).
Hate to say it, but they have completely wasted their time with trying to make realistic graphics, rather than something that is far more stylized with realistic lighting and shading.
There is a very good reason as to why Pixar (animation/3D genius's) do not aim for realistic art direction.
From the sounds of it, Beowulf probably isn't that great of a story to do a movie on, but I can see it doing well enough.
