Dear John-This movie is pretty much like The Notebook. It's based off a book by Nicholas Sparks (same guy who wrote NB), so yeah, it seems like he has a formulaic approach to his books if the movies are an accurate representation of them. The two leads (Channing Tatum and Amanda Seyfried) meet in a similar way that the two leads in the NB did. The male lead only has his dad. They are from humble roots. The chick is from wealthier roots. He goes off into military, they don't talk, she goes with another man. Years down the line, blah blah blah. If you've seen the Notebook, you've seen this movie, basically. I still think it's worth a watch. I was glad to see Channing Tatum take a role where there was more emotion shown due to his being labeled as vapid in personality when acting. He had a couple of emotional scenes, in which one of them, I thought he did a great job. As far as chick movies go, not bad at all.
The very name of this movie leads me to believe it's sentimental horseshit.
