Say anything is an older movie, but a great one at that. I'm not sure really why it's captured my appreciation, but it's simplicity and classic love story vs the parents is a no lose plot.
Of coarse it's all famous picture of him holding the boom box over his head outside her window is this movies claim to fame. Actually a lot of people have no idea what the movie is or haven't even heard of it, but recognize that image.
I would encourage anybody who likes a classic, maybe a little cheesy movie that will warm your heart and take you back to the high school sweetheart days and thinking that life was always going to be so simple. It does a great job of capturing the time period and the unrealistic reality of life at that age.
