The Thing directed by John Carpenter is one of my all time favorite movies, and the that movie was based on Who Goes There? by John W. Campbell. This book, Frozen Hell, is Who Goes There? the original way Campbell intended it to be before editing it to be shorter. Now I haven't read the original but I can see why he edited it down, there's a lot of "fluff" here and felt like it took away from the tension at parts. It was still enjoyable to read through but I'd say  the movie is better than the source material.
