putting it simply if you are a fan of the franchise you must own this, i love horror documentaries, Halloween 25 Years of Terror, His name was jason were superb, this is equally as good but it is so in depth it runs for about 5 hours, going through every film individually the ups and downs problems on set, how they did certain effects, you honestly will not want to pause it or anything. at a tenner it is well worth it, i also cant believe how hot some of the actresses look now apart from one or 2 mentioned by the previous reviewer.
