Not entirely disagree with OP, sometimes facial animations got slightly over the top, but I presume they will refine them, complete animations sequences to be more fluid, and more importantly add variations and "levels" of expressions (like horror faces will hopefully range between "a bit disgusted" and "scared to death").
Besides facial features are really good (textures and shaders especially), and I love seeing my chars subtly react to what is said to them (it recalls me Mass Effect system).
I'm confident about many animations not yet added ; facial animations of companions look pretty much complete to me wich concurs to bring them lifelike. Good job on this !
