We bring back our film genre expert, Chris Vander Kaay (Author of "Spoiler Alert!: The Badass Book of Movie Plots: Why We All Love Hollywood Cliches") for a monthly series of what he calls "Not Quite a Genre", lists of re-occuring themes, events, actions, and tropes that can connection to similar types of films. This first round of "Not Quite a Genre" is called "Ding Dong Die" movies centered on one locations, preferably a home, where villains appear at the door to wreak havoc. We list several films that meet this criteria giving out advise on which films to seek out and which ones to avoid. No spoilers in these episodes.
