The story follows Portland restaurateur Nate, whose world is turned upside down when he comes back from a business trip to find out that his best friend and roommate, Jimmy, is now dating his newly singly mother. To make matters worse, Nate';;;;;;s previously disinterested dad, Harrison is now determined to win Lydia back and isn';;;;;;t afraid to use Nate to get what he wants. Stuck between his family feud and his best friend';;;;;;s first serious relationship, Nate';;;;;;s 'new normal' forever changes his relationships with his parents, and severely handicaps his own dating life.
With its nonstop wisecracks about hooking up, body parts, and pop culture references, Significant Mother feels like a Millennial version of Three's Company.
The one-note premise wears thin very quickly because there is no way that anyone can root for the relationship at the center of it. It is not cool to sleep with your best friend's parent.
A high-concept but low-funny sitcom about a young man whose mother starts sleeping with his lifelong best friend, Significant Mother is vulgar, tasteless and strained.
