I want to beat Blackhawkswincup to something and I watched the last one last night, so...
Child's Play (1988) - 7/10 - This was both terrifying and original in 1988. There's something really basic about the fear that we have for things like dolls coming alive. It's harder to take the original seriously nowadays, especially with how campy some of the sequels were, but I think that it's still effective and I'm not going to judge it for not totally holding up. I just remember being chilled to the bone seeing it in 1988. Fun fact: Roger Ebert gave it 3 out of 4 stars.
Child's Play 2 (1990) - 6/10 - It's not as terrifying, but it adds more humor and a toy factory. It's a step down, but still a fun sequel.
Child's Play 3 (1991) - 4/10 - The military academy setting at least changed things up a little, but the shtick started to get old. Don Mancini, himself, said that he was running out of ideas.
Bride of Chucky (1998) - 5/10 - Chucky gets a female sidekick. This entry marked the turn towards comedy and parody. I kind of detest that change of direction, but I have to admit that this film was kind of entertaining. I can't say that I liked it, but it's hard to dislike something that makes fun of itself.
Seed of Chucky (2004) - 3/10 - Ok, I stand corrected. I can dislike something that makes fun of itself. This one ratcheted up the absurdity and comedy and went too far, becoming stupid. Glan (what kind of name is that?) is a really creepy looking (in a bad way) doll that travels to Hollywood to find his parents, but Chucky is disappointed in his son's sweetness and innocence and tries to teach him the ways of being evil. Enough said.
Curse of Chucky (2013) - 7/10 - The franchise returns to its horror roots. I really liked this one. It was ingenious to put the heroine in a wheelchair, as that makes her a lot more vulnerable, especially to a 3-foot doll. This is easily the 2nd best in the franchise and actually stands as a pretty good horror film in general. Fun fact: the heroine is the daughter of Brad Dourif (the voice of Chucky since the original).
Cult of Chucky (2017) - 5/10 - This one picks up after the last one, but slips a little back into the comedy and "hard to take seriously" elements that defined 'Bride' and 'Seed'. There's even a twist/cameo that directly links to those films and suggests that these last two are part of that continuum and not as much of a reboot as we might've assumed. It's really not bad, but was disappointing after how good 'Curse' was. It was nice to see the guy who played Andy in the first two Child's Play return and have a fairly sizable role, though.
Child's Play (2019) - 4/10 - This is pretty much a remake of the original, but, notably, the first entry in the franchise to be made without Don Mancini's involvement and the first to not be about a possessed doll. Instead, Chucky is simply a high tech doll that learns to be bad as part of its AI. His motives never really seem evil, just misguided, like an algorithm run amok. That ends up making him not very scary. He's also not that funny. The funny bits of the movie tend to be jokes added in that have nothing to do with the doll. If the doll known for being evil and funny is neither, what are you left with? It was also a bit too conspicuous that the movie was trying to copy Stranger Things by having the plot turn into four diverse 13-year-olds (a white boy, a redhead girl, a black boy and an overweight boy) teaming up to stop Chucky. A lot of people seem to like this entry, but I didn't.
In retrospect, it strikes me that the Child's Play movies range from bad to good, but not from awful to great like some of the other horror franchises do. There isn't that "great" entry like the original "Halloween" or "A Nightmare on Elm Street," but there isn't that one awful entry with no redeemable qualities like "Halloween Resurrection" or "Freddy's Dead: The Final Nightmare." Even the worst, "Seed of Chucky," has a "so bad it's good quality" and can be enjoyable if you're in the right mood for it.
