In its third season, the "1980-something" family comedy inspired by the life of showrunner Adam F. Goldberg has continued to find its grove. The Sony Pictures Television-produced comedy will return for its fourth season after it has helped solidify ABC's Wednesday night comedy block. This week, the network tested the comedy starring Wendi McLendon-Covey and Jeff Garlin in the 8 p.m. slot, where its Dirty Dancing-themed tribute episode tipped up week-over-week and bested The Middle in the time slot with an impressive 2.0 among the adults 18-49 demo.
