I have been watching the Chucky movies ever since the first one, and I am one to say that the franchise has been on a downward slide for a long, long time. Granted, I haven't been much of a fan actually, although most of the movies are enjoyable for what they were, but never reaching anywhere near along the likes of Jason Voorhees or Freddy Krueger.
"Cult of Chucky" is, at best, a less than mediocre movie. They should have stopped this franchise a long time ago. It is now at a point where it starts to become embarrassing to the franchise.
So now Chucky can suddenly possess multiple bodies at once? Right, sure, evolution, why not?
I will admit that the actors and actresses in "Cult of Chucky" did put on some good acting performances. And they actually assembled a good cast for portraying the various characters and roles throughout the movie.
The movie definitely has good special effects, which also do carry the movie quite a way.
When it comes down to it, then "Cult of Chucky" wasn't a particularly thrilling addition to the "Child's Play" franchise, nor was it a particularly memorable movie by or in itself.
