While simple, I think they add the sense of motion in a very solvent way. It's weird how a simple hint at motion feel the images feel more alive, or at least for me it's even a bigger turn on, especially the scene with Jeremy and Louise, damn that was already one of my favourites but with the animation it's even better. I hope she sticks with doing them, I think it adds to the game's quality and experience and many other 3D games I've played use the same 2 frame technique with less stellar results
