"Seed of Chucky" isn't the strongest of the movies in the "Child's Play" franchise. Why? Well, because they tried a bit too hard to incorporate way too much comedy. Don't get me wrong here, it is still an adequate movie, and the other "Child's Play" movies also do have elements of humor in them, but it was just a bit too much in "Seed of Chucky".
As for the story in "Seed of Chucky", well I will say that it overall felt like the soup was a bit too thin, and they should have stopped the franchise a while back.
The acting in the movie was good, though, as it has been in the many previous "Child's Play" movies too. But there is no doubt about the fact that it was Brad Dourif and Jennifer Tilly who carried the movie all the way.
Director Don Mancini had cut down on killings in "Seed of Chucky" compared to the previous movies, and instead putting most of the focus on the dysfunctional relationship between Chucky, Tiffany and their odd son Glenn.
While it is still an entertaining movie, it was just lacking the elements of the early years in the franchise, and you can say that "Seed of Chucky" sort of is a light variant of the "Child's Play" movies. As such, I am rating it a mediocre five out of ten stars.
