I thought it was Bad. 
 Augustus and Hazel were the only two people I remember, and I barely remember them. They were both the same! As are all of John Green's characters, if I remember correctly. They like to read, and they're really pretentious. That is the formula of their characters, and that is how they bonded. 
 I really hate pretentious Intellectual Teens(tm) who think that they are better than other people. 
 "It's a metaphor!" 
 Augustus trilled. 
 "My thoughts are stars I cannot fathom into constellations!" 
 he mused, and I immediately hated him. 
 I also found this gem of a quote in another review: 
 "I believe the universe wants to be noticed. I think the universe is improbably biased toward the consciousness, that it rewards intelligence in part because the universe enjoys its elegance being observed. And who am I, living in the middle of history, to tell the universe that it-or my observation of it-is temporary?" 
 It rewards intelligence? This is the kinda worst shit ever that really grinds on me. Just? Shut the fuck up! I said this in my Looking for Alaska review, and I will say it again... John Green really needs to stop jerking himself off to his Above Average Intelligence and Nerd Culture... kinda embarrassing. 
 Really, I don't remember much more of this. All I remember is that one of them died, and everything was sad, and everything was boring. I didn't feel it. 
 And no, I have a great respect for cancer sufferers, survivors and people who unfortunately did not make it through. This book wasn't about cancer, and I did not believe it true.
