I liked this episode. It was quite a bit different the short is based on, but it is still good. Norton is much more developed compared to the story. I thought this change was well merited because he is the central character of the episode so it gives the viewer a character to gravitate towards and support. I do agree that the whole connection with Irma's grandparents is a bit to much. However I thought the ending was amazing. I interpreted the scene as Norton and Irma hallucinating because they were out of oxogen, however, i can understand why some people are confused, it is a bit open ended.
