I do find it a bit simaller to Titanic, but in Titanic; Old Rose is telling the story but in the Notebook, Noah is telling the story to Ally. And also, Jack dies, Noah does not. Also, the love story between Jack and Ross is very different to the one of Ally and Noah, Jack and Rose do not get into huge fights and do not leave each other, but Noah and Ally do. But in both movies; both couples love each other very much; they're their true loves. It's just in The Notebook, it takes Ally and Noah a lot of time to figure it out! But in the end of Titanic; Ross reunites with Jack after 84 years:) while Noah and Ally die together.
They are a little alike. but they both are to very different movies. Noah was telling their story to try to get Allie to remember. Rose told her story to more the one person because they asked her to. yes both Rose & Allie were at one point engaged to other but at least the guy Allie were was engaged to was a nice guy and cared about her. Cal however was horrible to Rose
