Movie creatures

Spent the day at an effects house looking at creature designs today. I finally realized why I dislike movie creatures in general. It's because they are art-directed from the ground-up. In other words, their anatomy, proportion and design owes less to an understanding of animals and more to their function in a film. They are cartoon creatures. Real creatures don't look inherently "evil" or "funny" or "good." So the problem with many movie monsters is that their designs are poorly performed. Like one-note cartoon villains, they exist solely to fulfill their function with scary eyes, evil wings and sharp talons. A really terrifying creature would be like a real animal--it would have a hint of beauty, a touch of the mundane and no immediately apparent cinematic value.
