I'm not going to do a list for this one, I just want to say a few things about this story.
The movie was unnecessarily long. I enjoyed the short story much better. There were no unnecessary characters. It had a pretty good grasp of how people actually are. There was a romance in the story, but it was much more realistic than the one in the movie. The story really is an interesting concept and I would recommend reading it if you have a little time and want to read something short.
Overall, I was not super impressed, but I am not unhappy with the story. I am neutral... but might be slightly leaning towards the positive side of things.
