John Green has such a fascinating voice. Colin was such a weird adorable character, much like Spock or Brennan from Bones, who express themselves through pure information all the time. I loved the billions of footnotes, they were so entertaining, but didn't take away from the story. The one 'shocker' type twist in the plot, didn't shock me since there was (I believed) plenty of foreshadowing. But Colin learning how to tell a proper story, as well as the incorporation of stories of the two major Katherines flowed beautifully. Oh John Green, why must you be so fantastic?
