2.5 stars. 
 First off, let me say that I adore Fitzgerald's writing. I thought Gatsby was one of the most beautiful books I have ever read. However, I didn't like this book. At all. The characters had no character! A moment that this really annoyed me was at the very beginning when the father is shown his son and he is an old man. Wouldn't you be a little bit... well, no it's not? Instead, he carries it as if it is an inconvenience and goes out to buy him clothes? I just thought that was way too unrealistic. I get that it is a short story so can't go into a whole chapter of realistic character development and emotion and disbelief but I couldn't move past it. 
 Even throughout the rest of the book when I was supposed to sympathise with Benjamin, I couldn't bring myself to. Only perhaps at the end when he is a baby did it garner some reaction from me which is why my rating isn't one star. The ending was quite well done. 
 An interesting concept which maybe should have been better developed as a full length novel. 
 I hope this is the last Fitzgerald book that I don't like and enjoy the rest of them.
