Jennifer Aniston is an unhappily unmarried 40-year-old (way to stretch those acting talents, Jen) who decides to have a baby with artificial insemination. Through a wacky set of circumstances, her best male friend (Jason Bateman) substitutes his own baby formula for her sperm donor sample. Seven years later, they hook back up, and he considers spilling his secret. The premise is ridiculous (not to mention similar to The Back-Up Plan and The Kids Are All Right). But the cast is solid, turning this into an enjoyably offbeat romantic comedy.101 minutes PG-13.
