A brief recap of Amityville movies... there were a few movies about a haunted house, then in the 3rd movie, the house blew up. At part 4 and just about every movie after that, it was about some random cursed items from the house winding up in cities all over the country. It didn't really matter after a certain point, and then the b-movie companies went hog-wild with it, just like they did with shark movies. There are infinity Amityville movies now, and this is one of them.

I was actually wondering wtf this movie had to do with Amityville, but they clear that up for you: it's haunted wine from the Amityville house. And now it ends up in the hands of a Karen in California.

Honestly, who cares about the Amityville part. The first half of this movie is straight-up about a horrible Karen being a horrible person, and that works all on its own. The whole idea of our Karen is reminiscent of how a Mink Stole would react in Desperate Living. I think Mink might be the OG Karen actually.

Our Karen is played by Lauren Francesca, who is actually pretty hot and therefore easy to watch, no matter how much of a cunt she is being. Besides, you don't ever actually hate her, because her depiction is too funny to take seriously. "Oh, I forgot to harass the gardener today!"

Eventually, she drinks enough of that tainted wine to get possessed and/or go insane, and she starts killing her stupid friends over trivial matters. It's basically a perfect plot, though the execution is still only mildly amusing. Shit rating on imdb makes for some good points though.
