I discovered something important about myself when I watched The Switch. I discovered that I can endure 101 minutes of pure saccharine filmmaking without catching The Diabetes. I have no problem with earnest filmmaking that’s unafraid to wear its heart on its sleeve. I do have a problem with transparently manipulative filmmaking that wastes the comic talents of its lead actor. A few clever one-liners sneak past this sitcom-level humor, but The Switch stands more as an endurance test of sugary storytelling rather than a heart-warming picture.
