In the trailer, Laurie said, "Maybe if the only way he can die, is if I die too." They should have done that for the ending, both of them should've died. The only things I like about this movie is the soundtrack, references, and kills ! :D
Edit : I'm really surprised neither of the characters in the movie said "Evil Dies Tonight." Also Laurie said that "Maybe if the only way he can die, is if I die too." she also said this line in Halloween Kills. Halloween Kills was a fun movie, and Halloween Returns is my favorite out of the trilogy. The five Jack-O-Lanterns in the opening credits to Halloween Ends could represent the five timelines in the series, and the sixth regular pumpkin that opens COULD possibly mean there is going to be a new timeline in the series. Who knows ?
