My current favorite graphic novel is Adrian Tomine’s Shortcomings
Without giving too much away (or sounding like a press release), Shortcomings is the story of a relationship gone sour, and the rather complicated ways we fool ourselves and the ones we love. Adrian has mastered what might be called “acting” on the comics page. His body language is subtle and precise, his characters moving through his pages with an exactitude rarely seen in the medium. All told, this is a case study in incisive characterization and perfect storytelling. This site has background info, notes and other goodies. Check it out and then go buy this book.
