LIL' DISCLAIMER: I lowered my initial rating of 5 stars (July 2015) to 3 stars (November 2016). No I didn't re-read this but I think looking back on the novels you have read is a wonderful thing and when you realize that a book is def not one of your favorites because you forgot a lot about it and see flaws now that you didn't see then and so I see no problem with downgrading a book without a re-read. :) 
 I say it now and I said it then: Cat is one of the most relatable characters I have encountered in fiction so far. Of course it is easier to create a relatable character in a contemporary setting than in a high fantasy one but still I was impressed by how well Rowell managed to display those angsty anxious vibes of an introverted girl who is a little overwhelmed by the new setting of a college campus. When I read this I was in my 2rd semester at college and still feeling the same things that Cat felt. Not wanting to go to the cafeteria. Fear of missing out on social events, fear of finding no friends at all. The feeling that book characters were better and safer friends than new people from uni. I loved how authentic Cat's feelings were. 
 The rest of the story (in hindsight) fell really flat for me. I totally despised the Fanfiction parts of Snow & Baz because they were so poorly written and didn't ADD ANYTHING TO THE STORY LIKE WTF (I kept reading them because I thought there may be parallels to Cat's RL storyline but nope they were just there as an advertisment for Carry On probably ugh bah no). The lovestory also really didn't do it for me, sure it was cute, but very stereotypical and that's were my biggest issues starts: Cat doesn't do shit (which is totally ok when you're so introverted and shy etc etc) but everything worked out for her perfectly because people just loved her and interacted with her... that is not real life or at least not my experience... if you're not going to talk to people, people won't talk to you. that's the truth. deal with it! 
 She got the perfect boyfriend, internet fame, a clique - it was just too cliche of a happy ending and would have liked it better if her struggle would have been explored more and how she overcame her fears and not everyone sticking things up her arse... sorrynotsorry
