- Alternative Character Interpretation: Though listed under Catharsis Factor, there is a really serious undertone to Andy's questionable sanity. While the small armory and isolationism is a reasonable response for one's safety from an immortal serial killer after you; it's another oddity to keep that same serial killer's head with you as company despite torturing it. Is Andy going off the deep end with the resurgence of Chucky? Or is he taking the steps necessary to keep himself (and by extension) the world safe from Chucky? Or both?
- Ass Pull: The reveal that Chucky can possess multiple dolls at once.
- Big-Lipped Alligator Moment: Malcom and Nica have sex just after meeting, and the scene is never made reference to again. They don't even show anymore romantic interest in each other afterwards.
- Catharsis Factor: After all the torture Chucky's put Andy through in the previous films, watching Andy take his long-deserved vengeance on Chucky, while terrifying, is immensely satisfying.
- Even Better Sequel: To Curse, due to a more interesting and creative plotline, better performances from the cast, making Chucky's kills more sympathetic (except Dr. Foley) in comparison to past victims and having Kyle from 2 reappear, among other things.
- Fridge Horror: In the ending, Andy is out of weapons and locked in the insane asylum by one Chucky, who's successfully possessed Nica... with another Chucky doll still alive and present to do God knows what to Andy. Like, say, finally pulling off the Grand Theft Me Andy must have spent years fearing. To add to that, if Chucky did finally possess Andy, he could then easily target Andy's mom, Detective Mike, and Kyle to continue his revenge, with them none the wiser until it's too late. The Bad Guy Wins indeed.
- Heartwarming Moments: The Reveal that Andy tried to clear Nica's name.
- Hilarious in Hindsight:
- One of this film's plot points was accidentally predicted in Phelous and The Nostalgia Critic's review of Child's Play 3.Critic: Oh no! It's the rise of the Chucky clone army!
- In Child's Play 3, Chucky nearly gets a haircut. In this film, Andy's Chucky doll has a buzzcut in order for Andy to distinguish it from the other Chuckies.
- In the Japanese dub, Bin Shimada's role as Chucky comes as this since he previously voiced Juda, a mass-murdering effeminate psycho. In this movie, he voices another psycho, without the effeminate part.
- Also from the same dub, Chie Nakamura's role as Nica is pretty hilarious as she voiced Mia Fey/Chihiro Ayasato in the animated adaptation of Ace Attorney, since she has the ability of possess the body of her younger sister Maya/Mayoi after she was murdered earlier in either the games and the anime. In this film, she is the one who gets possessed instead.
- Nica's actress is the daughter of Chucky's actor, he was already a part of her to begin with.
- One of this film's plot points was accidentally predicted in Phelous and The Nostalgia Critic's review of Child's Play 3.
- Jerkass Woobie: Claire in her final moments.
- Nightmare Fuel: See here.
- Rescued from the Scrappy Heap: Picking up where Curse left off, Chucky is finally back to being his perfect balance of murderously insane, without overdoing on the jokes like Seed did.
- They Wasted a Perfectly Good Plot: Based on the synopsis, one would suspect Andy and Nica to meet pretty early in the film and possibly team up. They don't meet until the end of the movie, after Chucky's possessed her.
