Brent and the team at Disney Feature Animation have always pushed complexity like crazy. Most people keep telling them to just think procedurally or reuse elements, but Brent prefers to let the artists do whatever they want and the system should handle it. Since cores are cheaper than humans this is a good long-term tradeoff, but YMMV since very few studios would bother doing so much explicit detail (as opposed to procedurally tweaked variations).
