Channing Tatum and Amanda Seyfried in Dear JohnDEAR JOHN

Since no one's been pressing a gun to my head, I haven't read Nicholas Sparks' Dear John, which concerns a pair of star-crossed lovers whose romance is derailed by the young man's Army tenure. I have, however, seen director Lasse Hallström's screen version, which apparently follows the novel's blueprint faithfully (albeit with an altered ending), so permit me a question: Does Sparks have absolutely no shame?
