The concept of The Greatest Hits is far more compelling than its execution because it never commits to the interesting idea at its core, treating it as an obstacle rather than exploring its potential. We also aren't given enough time with protagonist Harriet’s (Lucy Boynton) former boyfriend, so I didn’t care about him or understand her infatuation with their relationship. As soon as the new love interest (Justin H. Min) is introduced, it's obvious what will happen; however, he and Harriet lack romantic chemistry, which is a shame since I can forgive pretty much anything in a romance if the leads have a strong connection.
