I enjoyed the book. It even made me cry a little bit (although, I read it at a sensitive time of the month, if you know what I mean). But I feel like it's way, way, way over-hyped. John Green's writing is good, but I just don't understand the fuss about him. He comes off as seriously arrogant to me and more than a bit pretentious.
The Fault in Our Stars definitely wasn't without it's faults. People are idealizing this book to extremes. I don't know any teenagers, let alone adults, that talk as well as Hazel and Augustus. It made them feel like they weren't real. That's not to say they weren't amazingly well-rounded characters, but it was hard to picture a teenager talking like them. I also felt like John Green's writing was sometimes a bit too wordy, as if he was trying too hard to win some literary prizes, if you know what I mean.
All in all, it was a pretty good book. It wasn't the worst thing I've ever read, that's for sure. It was predictable, and it sure as hell wasn't anything groundbreaking in literature like people are making it seem. I enjoyed reading it, but I'm not freaking out like everyone else seems to be. But that's just me, read it yourself and see what you think!
