Well, for one, my first rewatch was after I got back from a trip to Chicago so that added an element to it personally. But, the third was solely based off of wanted to watch it again. The second and third time I definitely caught more. It's such a fast paced show, you are bound to miss little details. But beyond that, I just love the characters, I love the story and the feel of it. It's funny, heartfelt, and personal. It's just a great show that definitely doesn't deteriorate on repeat viewings.
