Curse of Chucky - I really liked this one. Been a fan of this series since the beginning, and it has the best track record for sequels. Only the third one is an outright stinker, the rest are good, although Seed had problems. This one takes it back to more of a horror tone like the first one. And while after Bride and Seed were more humorous I wouldn't have expected that to work, it really does. Performances are good, particularly from Fiona Dourif.
Because there is no origin to get out of the way, or need to explain why he's still alive after the last one, Chucky can be present from the very beginning. He provides a nice palpable tension throughout.
One thing I have to particularly applaud the filmmakers for is the look of Chucky himself. In the other movies (especially the first two) it always kinda bugged me the difference between his look when he is just the nearly motionless doll and when he is full animatronic Chucky. This was due to the limitations of the plastics at the time, but still they have improved it so his skin texture doesn't shift rapidly.
I did have some issues though:
Later in the movie Chucky gets his head knocked off and it's just a doll stump attachment. What? It's established in this series that he gets more human (becoming more flesh and blood) as he spends time in a doll body. And by now he's been in that doll's body since Child's Play 3!
I also didn't get why he would perform the soul transference spell on the girl at all, since at the end of Seed he decided he liked being "Chucky the killer doll" and wanted to stay that way. It was one of my favorite parts of that movie in fact. Not to mention that the spell shouldn't work (and he would know this) because he is still in the doll body from part 3 and the only kid it could have worked on was the black kid in that one. And it's too late for even that.
The after credits sequence with Andy grown up seems to contradict that scene anyway. The only thing I can think of is if Chucky figured out some new aspect of the spell and did something different with it. But the only way to know is see what they have in store for next time.
I didn't like the whole flashback sequence showing the family's connection to Charles Lee Ray. It came way too late in the movie, took too long, and didn't seem very well thought out. Also, there is just no way to ignore the blatant age difference in Brad Dourif from the first movie to this one. Especially when they actually include some footage from the first movie!
But overall I really liked it and would recommend it to fans of the series. Definitely a great way to reinvigorate the franchise, and I now welcome them to make more.
