Moulin Rouge---one of my favorite movies ever not just in this specific genre. The music is fun, the directing is fabulous and the love story is told to such perfection by Ewan and Nicole...Just love this movie.
Eternal Sunshine of the Spotless Mind
The concept of this movie is sad, hopeful and romantic. Just the idea that you could wipe all your memories of someone away but still somehow, someway find a way to still meet that person again---Destiny, fate all of that. Romantic definitely.
