I like Dr. George Huang on "Law & Order: SVU," played by B.D. Wong. I always look to see if he's going to be in the show (or if it's an earlier show, before he was added and then I often won't watch).

He adds some sanity in there where the detectives are just out for blood and I feel "safer" if he has his say and balances what's going on, figures out the person is putting on an act or is hurting for real.
