Judy Greer, finally getting top billing in a show, has been one of the joys of the spring season, playing a high school guidance counselor in the charming and funny ABC comedy “Miss Guided,” executive-produced by Ashton Kutcher (great in Episode 2). “This is a school, not a Whitesnake video.” The writing is terrific too. ABC, which hopefully knows what a keeper it has, has been running through MG’s seven-episode season quickly (back-to-back episodes air March 27 and April 3), so if you haven’t been watching, get to ABC.com and catch up.
