3- 
 The faults, the few stars. 
 As in his previous books (Paper Towns = good, Alaska = better than good, TFIOS = better than best) 
 John Green serves us a cocktail of the same heartfelt, witty, YA ingredients but has the combinations, the portions, the shaking wrong. 
 This is when a one trick pony loses its sharpness. Hopefully it's temporary. 
 Disappointing. Yet no 2 star rating, because, hey it's still John Green, best of all YA writers, so you'll still have a laugh here and a wow there.
