When done properly, a romantic subplot can be an excellent addition to many TV shows, but these romance storylines hurt their shows. Audiences love to see when a heartwarming relationship begins to blossom between two beloved characters, especially when their deep connection is something that has been suggested throughout the series. Unfortunately, not every onscreen relationship is built equally. While some romance subplots can dramatically improve the quality of a show, others can lower it just as easily.
