Whoa, whoa, whoa. We're going to have to have a whole side conversation about what constitutes a Rom-Com. Clueless and Groundhog's Day? That sublist of four? That's not really what I think of when I think Rom-Com.
WikipediaRomantic comedy films are films with light-hearted, humorous plotlines, centered on romantic ideals such as that true love is able to surmount most obstacles. One dictionary definition is "a funny movie, play, or television program about a love story that ends happily". Another definition states that its "primary distinguishing feature is a love plot in which two sympathetic and well-matched lovers are united or reconciled".

Remove the witty banter from Clueless and Groundhog Day and you have essentially, romantic comedies. The entire premise of Groundhog Day is that only love can break his recurring nightmare. Clueless is about her quest to find a boy when the "right guy" lives in her house the entire time.
Sorry man, but those are rom-com's, just with better writers.
