Imagine this - a Tarantino fan is asked to write an eight hour season of a TV show, set in a log cabin for budget purposes.
They write it, paying homage to Tarantino films in a few different ways, casting some of his usual players. They do their best to be Tarantino - there are too many self-indulgent speeches, the characters all talk the same flowery lingo, every question or fact has to be asked/given in some repetitive, distracting, and unbelievably self-conscious way. Yet, it doesn't have any of the verve or quotability of an actual Tarantino project.
You eventually end up buying the DVD set of this series in a supermarket bargain bin. At home, you notice that one disc is labelled "Deleted Scenes". You put the disc in - check the time, and there are 180 minutes of deleted scenes. You watch them all in sequence.
THAT is exactly the experience of watching The Hateful Eight.
