Josh Gordon and Will Speck have made the third sperm-donor comedy this year, and in some ways it's the best. The set-up alone has some of the funniest semen humor since There's Something About Mary.
Kassie (Jennifer Aniston) feels the clock running out, and to the dismay of her friend Wally (Jason Bateman), who has all the joie de vivre of Eeyore, she decides on artificial insemination. At her "Pregnancy Party," Wally gets loaded and stumbles onto the donor's offering, and the last thing he remembers is the name "Diane Sawyer."
He doesn't see Kassie again till seven years later, when she returns with Sebastian (Thomas Robinson), who's the kind of weird child you meet in real life — he collects picture frames, for example — but never in the movies. Of course, Wally bonds with him. Could he also be in love with Kassie?
The Switch is not as challenging as The Kids Are All Right, but the kid is even better.
