It's a risky tattoo on a sixty something friend that pushes desperate parents (Kathy Bates and Terry Bradshaw) to hire Sarah Jessica Parker to romance Matthew McConaughey out and give them an empty nest.
Mom Bates continues to clean and fold her 35 year-old son's clothes, make his bed, cook his breakfast and pack a snack into his backpack as he goes off to play with his thirty something friends.
He plays with girls - it's romance up to the point when they have "that look," and then he brings them home so they will discover his living arrangements and get out while the getting is good. He's a silly little boy with some reason as we learn later, but he is shallow in relationships except for those with his two buddies.
Zooey Deschanel on the other hand is brutally honest and not a warm loving creature, in fact she wants to Kill a Mocking Bird, and makes the attempt with her Red Ryder, compass in the stock air gun.
Everyone is superficial; only Kathy Bates has a scene with feeling concerning her husband. Sarah Jessica Parker is the hired hand who has a plan to get him out of the house. She is a female Hitch.
It all falls apart of course because romance wins out even after a lizzard bite and public exposure play out the final scene in which we can easily guess who will get together.
