This is where they started getting into Halloween 5 and 6 territory
When I saw the women in the garage, I lost all hope for these films. What ruins the mystery and creepiness of a horror franchise, especially one with lots of potential, is they go into these cliche "sold my/his/her soul to the devil" and creepy, satanist cult type story. This was proven even more in the fourth film. Wish they had gone with a totally new story with different characters/different entity with no connection to Katie's story. It already got old in the second film.
