I just finished reading this story, and it was quite interesting and very different. I thought it did have some very beautiful passages within it. Though I did not completely understand just what the meaning behind the story was. I felt as if Benjamin did not really accomplish much or really develop or learn anything as the story progressed, his unusual case did not really seem to offer any true life lessons.
While it was unfair the way he was treated by others, particularly the various members of his own family, and I did feel bad the way in which they seemed to look upon him as if he was to blame, and simply purposefully trying to inconsistencies them all and all Benjamin did not come across as a truly sympathetic character.
I did not find his personality, or who he was as a person to be particularly likeable, and in many ways he did seem to be selfish and demanding, and while his condition was not his fault, on the other hand he failed to try and understand how others might be affected by the unusualness of his situation.
What struck me the most though and really turned me off, was the hypocritical way in which he treated his wife. When he was to the eye a man of 50 he was all too happy to marry a beautiful young woman in her 20's but as his age began to decline, and while she grew older and the roles became reversed, he grew scornful of her and ashamed to be seen with her. She was no longer his trophy wife and so he resented being tied down with her.
