First, I watched the movie of this work and then I read the short story. The subject itself is excellent; a person who ages backwards. In the movie there are a lot of symbols to be analyzed, most of which can be pragmatic. However, in the short story, I could not find any symbols or any metaphorical feature, which is surprising for me.
I loved both the movie and the short story but I need to add that the movie with its various characters and it’s hidden messages were much better than the short story and I guess it is due to the successful director of the movie, David Fincher.
As to the short story, I think it is worth reading. But I strongly recommend to watch the movie as well.
