What makes a film romantic? Is it the setting, the dialogue, the actors, the sex? And when your snuggling up next to your significant other this Valentine's Day, which films will you prefer to slide into the DVD player? Moviefone has assembled the definitive list -- the top 25 romance films of all time -- and now it's up to you to decide what they got right, what they got wrong and what they didn't get at all. Of course, Casablanca tops off the list at number one (is there a list in which Casablanca is not featured in the numero uno spot?), but following closely behind are Titanic (#2), Wuthering Heights (#3), An Affair to Remember (#4) and Gone with the Wind (#5). Obviously, when we're talking romance flicks, they don't make them like they used to.

When it comes to films made within the past few years, we don't find one until Brokeback Mountain shows up at number 12, followed by Eternal Sunshine of the Spotless Mind at number 15, and last year's Atonement at 18. Personally, I have a few issues with placement -- not so much with the films themselves -- like why Sleepless in Seattle is at 25 when it should've been higher. Films that didn't make the cut? Surprisingly, not many romantic comedies made the list. Even though they rely more on humor, some of us enjoy a little laughter with our cheesy romance. That being said, why not throw When Harry Met Sally a bone? Or even last year's Knocked Up? Either way, let us know what you think about the list below -- which films belong in different spots, which don't belong on the list at all and which are your favorites?
