Watched The Thing for the first time and was perusing its TV Tropes page which included a link to this under the trope 'perspective flip'. Read it the following night.
Really worth reading after watching the film. The film was good enough, and this is just a brilliant mini-novelisation, perfect length, really intriguing.
