Kassie, played by Jennifer Aniston, wants to have a baby as a single mother. She seeks a sperm doner to fulfil her task. All while her best friend Wally, Jason Bateman, despises her decision. During Kassie’s pregnancy party Wally drukenly and unknowingly switches the donor’s sperm with his own.
The story revolves more about Wally than Kassie. Fortunately because Bateman really steals the show, it also doesn’t hurt that the kid in the movie is adorable. Overall The switch is a decent romantic-comedy that has little romance and some comedy.
