I had just the opsite reaction with my therapist, I would be troubled by her lack of non-verbal "cues" for me to be able to read her with. She is great at the whole "therapist facade".

Took me a long time to adjust to someone I couldn't read, normally I'm really good at it, so this was SO frustrating.

Could be your therapist is projecting an "image" that he thinks will be most beneficial to you, you might want to talk to him about it.
