To answer your obvious question: No, Heigl didn't up and make a sequel to The Human Centipede. Though Life As We Know It is a type of horror movie: The maudlin mashing of two completely opposed genres -- romantic comedy and potentially serious family drama. It's like some studio executive was sitting in his office, trying to think of way for Heigl and co-star Josh Duhamel to meet-cute and landed on, "Let's kill off their best friends and leave them with a baby daughter!"
And so Life As We Know It uses a newborn baby as a plot device to bring two completely opposite people together. Which means poop jokes -- and lots of them. There is also a bit when Duhamel actually shoves the baby girl over in an attempt to distract her. Because wringing laughs out of faux-child abuse is kinda funny. And hey, it worked in The Hangover.
Anyway, Heigl is Heigl -- what you see is what you get -- and the supporting cast is loaded with recognizable faces (squint and you'll catch Mad Men bombshell Christina Hendricks as the doomed mother of Baby Poop Machine), but Life As We Know It looks odious. Literally.
VERDICT: Pass.
