This was probably the worst episode Modern Family has ever crated. I didn't laugh a single time.
Modern Family is one of the few comedy shows I really like. I love its cast and the its humor, but in "Dance Dance Relevation" all the characters were misused and all the storylines were terrible. I really don't want to talk about this episode anymore. Overall, a bad "year finale" for this show.
Nevertheless, every show delivers bad episodes now and then, and bad episodes are forgivable, so I really hope Modern Family comes back with a bang in January making me forget this week's twenty minutes.
