This is a bit tricky. Pretty much any genre can include romantic aspects, and while it's usually fairly obvious whether or not that is the primary aspect of the movie, sometimes it's a close call. And sometimes I'll put my reviews in other categories, such as musicals, or period pieces, or quirky, or seriocomedy, etc. Also, I eventually started a separate section for rom-coms, and moved some of the movies there that were originally listed here. There are, however, still some movies listed here that might be considered "romantic comedies," but I've left them here because they have more of a balance between comedy and drama. And... I don't really know what else to say.
