This might just be the most insightful movie about men. Watch if you are a guy and you will cringe endlessly from seeing yourself in the characters, and if you are a girl you should also watch it to laugh and understand the men around you better (yes, it is that insightful). Rob Gordon, a music fanatic who owns a record store, tells the stories of how his relationships ended, included the one ongoing. So if you are asking if this is a romantic comedy about a man trying to move on from a breakup, yes, it is. And it Works.
High Fidelity is in fact funny, interesting and comes with a unique look at relationships. But it is mostly simple and entertaining, and with perfect performances from John Cusack and Jack Black as well as an immaculate soundtrack, it is a must-watch.
