I have a friend who works at MPC in london who are handling the effects and the stuff hes seen says looks half and half, some shots look great such as a scene involving Bencio tied to chair infront of a load of spectators as he begins to change.
But some stuff apparently looks abit shit such as an animatroiic bear that looked so poor it had to be replaced with cgi.
I hope this is amazing, but in the hands of the guy who made Jurrasic park 3 it makes me a little worried
