I feel like "emotional but just doesn't make me feel the sentiment" scenes are an intentional specialty of westworld. There are enough "false" endings to emotional scenes (e.g., the beachfront scene in the final episode of s1) that the viewer is trained to question the authenticity of any emotion expressed by the hosts. You could say that that's really the crux of the whole series, and still an open question. The best modern successor to Philip Dick in that regard.
