I don't know what to say. I kind of feel like the odd one out. Everyone said how this book was worth reading, worth-crying for. How it was a heart-wrenching story. But it simply didn't touch me, I just couldn't feel for it. I was deeply disappointed by this book.(3 stars is not a bad rating !!!) 
 WHOA!Whoa! Calm Down! No need of cursing and throwing stones at me. Let me Have my Say first! 
 It was just my heart didn't pain, I couldn't feel emotional, and that coming from me is a very big thing, given that I cry reading the simplest of books and watching Frozen, Marley and Me and even Tangled! 
 Everyone reads and understands a book differently, maybe i concluded the book differently from you, but it didn't move me. Here are the reasons why: 
 FIRST: the characters didn't have any color in them, I didn't get to know their personalities. I am very sorry,(GOD save me!), but they were kind of lame.The book shows that Hazel is very Intelligent, but i don't fell so,instead she always throws tantrums. The way she quarreled with her parents, if i did the same thing to my parents, I would have been grounded for the whole of eternity. Now coming to Augustus, no I will not call him Gus, what kind of nickname is that, it sounds like Gas. He was a lot better than Hazel, and I respect his bravado in the Cigarette act. But exactly what made him love Hazel? And he was kind of weird too. 
 SECOND: the book was unrealistic, how would you feel if your friend often started taking in Victorian English or long monologues or suddenly started quoting Shakespeare with all the 'thy', thee','thou'. That doesn't mean I don't love old English or I don't love Shakespeare. He was a great writer. Try to reason with this example. Suppose one friend came to you and said, " Oh my heart betrays me, my love! I have fallen in a unconditional love with you. Such a pleasure it is to see a young and beautiful lady like you. You are like the song of songs, the star of stars, let me redeem myself by kissing your hand, as pure, as serene as the white lily in a river. My thoughts have become stars that I cannot fathom into constellations." Awkward ,right? It may have been romantic but what if he/she ALWAYS talks like that. Not Nice. Hazel and Augustus rarely went to school and they didn't even study properly. So how come they make such long monologues? I doubt that they even know what are monologues. 
 THIRD: the story plot was nice and the novel could have been epic if it was framed properly with Hazel's and Augustus's own words, not some random, elaborate words joined together. The story did not flow smoothly. It had so many bumps that it pains the reader to keep traveling along that treacherous road. It was just pieces linked with just a string, not weaved. Probably, John was too busy Vlogging, or whatever it is called. 
 FOURTH: Some of the quotes didn't make sense at all, and Hazel didn't have a tinge of logic and reasoning in her head. The quotes were just idiotic, sorry but I am thinking out loud here. "some infinities are bigger than other infinities". My reaction was : "WHAT???". Infinity means a thing which never ends, which never stops. How can you compare one Infinity with the other Infinity? How can you compare infinite positive integers with infinite negative integers? 
 John should probably take lessons from my Maths teacher. But, Beware John! She is very strict. 
 I tried so hard to like this book, to feel the emotions hidden inside, but no matter how much I tried, I was unable to wring out the emotions from the character's words , from the novel. A writer should pour all his/her heart in the book, the words bleeding with emotions, the heart thumping in each and every single page , and maybe John forgot to do so. And hey 3 stars is not a bad rating! I liked it but... I expected more. If u liked the book then its very good. I hope you loved the book and could swim to its depth. So keep reading nice books! 
 Someday i would give it another try, see if I can feel something and not just read like a robot, the words swimming in my eyes, having no depth. 
 Happy Reading! 
 Love,
