I haven't seen the first 2 movies you mentioned, Omar, but I don't think they're available on DVD yet. I would say the best romantic movie that's just plain good and isn't over-the-top is
Eternal Sunshine of the Spotless Mind. If you want something you haven't seen before, I recommend
Happy Accidents. It's a pretty unknown movie but I remember liking it and it is definitely a romance. Both my choices have a bit of a sci-fi spin to them, I don't know what that means. If you want just all out romance, you can't go wrong with
The Notebook.
