"Everyone has a different idea of what a "romance film" should be, which is understandable. There are all kinds of romances and like what Hugh Grant says in the intro to "Love Actually," love is really all around. Sometimes watching it melts our hearts, sometimes it makes us annoyed, sometimes it gives us thrills, or even makes us feel depressed. Love exists in all shapes and forms and filmmakers try to reflect that right from the beginning.
The year 2019 was not necessarily as strong as 2018, which had probably a bit more variety of great stories, but it was a fine year on its own as well and it brought us romance stories in its different forms as usual. Before we start, a dishonorable mention goes to "Last Christmas" because George Michael deserves a better movie. Then there is "Isn't It Romantic," which couldn't make into the list because the premise; that "Express Yourself" scene is pretty good, but it's just too underwhelming."
