'The Middle' (Wed., 8PM ET on ABC) is absolutely killing it the past couple of weeks with guest stars. Last week it was Norm MacDonald as Mike's slacker brother, and this week it was Molly Shannon as Frankie's passive aggressive sister, Janet.
When the Hecks head to Frankie's family's house for Thanksgiving, Janet immediately starts to use that horrible passive aggressive technique that we all hate and all no someone who does. More often than not, it's a relative who masks it with love.
So it was worth it when finally Frankie stood up to her and the two had a sincere fight, airing out the grievances that have been plaguing them most likely for years. Round it out with Marsha Mason and Jerry Van Dyke as the parents, and these are recurring characters we can truly be thankful for.
