I love this edition of Halloween (1978). I rushed to buy it after its release as it was the best idea ever. Essentially, the producers edited together the tv and theatrical versions of the movie together. Thus creating a more well rounded and fully visualized move.
For those not in the know, the original Halloween had additional footage filmed to make up for the parts cut for the tv version. These were more dramatic scenes that added in more character creation and world building.
It takes an already good movie and makes it better.
