I definitely have it. In real life I can read happiness, sadness, anger, and shock. Sometimes confusion. I never realized until lately that I've never seen more than that. And that's usually all the emotions I can draw without reference.
In tv although I often can't name them I see an incredible range of tiny emotions. Eyebrows lifting, eyes darting, smirks. I think it's because the characters aren't talking to me and I can look at their entire face/eyes and I can pause/repeat when I don't understand jokes. The more I rewatch an episode the more I see (I don't catch everything the first time).
Strangely with books I have a hard time imagining faces unless the book has a movie, keeping track of them all is close to impossible, and I can rarely imagine their expressions unless again, the book has a movie.
Edit: And yes, if I can relate I get all emotional. But if I can't, it's like I can put on their shoes but not their thoughts, so I don't feel anything. If theirs animals involved I'll cry like a baby. I hated Disney movies of animals as a child because of this reason.
