SPOILER ALERT: The following article discusses, in detail, the ending of Halloween (2018).
David Gordon Green’s Halloween is now, if you don’t adjust for inflation, the most financially successful movie in the whole franchise, outgrossing the previous record-holder, Rob Zombie’s 2007 remake, in its very first weekend. That’s great news for Halloween fans, who are clearly desperate for more old-fashioned entries in this iconic, influential franchise.
But it’s bad news for the filmmakers, who have written themselves into a hole. Literally.
Halloween (2018) retconned the entire franchise, removing all the supernatural elements, and even the soap operatic revelation that Laurie Strode (Jamie Lee Curtis) was Michael Myers’s sister. Over the course of the new film Myers escapes, goes on a killing spree, and winds up at Laurie’s house. But instead of killing Laurie and her daughter and her granddaughter, Myers gets trapped in Laurie’s basement. She seals off the door, and sets the house on fire, seemingly killing the boogeyman forever.
