I don't know where to start on this show. It's so different than any other comedy shows out there and is on a different level in terms of writing, acting, detailing and what not.
But the most important part of the show that moves you is the life in those characters. The show reached it's peak in 4th and 5th seasons and their each one of the episodes are gems. Ever dialogue is intricately written and complements the character that has already been established. I've watched each episodes 5 times atleast and everytime I rewatch it I have a different favorite character. Although my all time favorite is Phil Dunphy. The show is ending after 11th season. But the episodes have enough content that you can rewatch it numerous times and still end up with a different feeling.
