You have this premise with Chucky going around killing inmates in a lunatic asylum, in the best place on earth where no one would believe a living doll was going around killing people, and especially with Nica being there and being framed for it after what she went through. That alone could have been the plot for the movie. Nothing too special, but at least there'd be some good tension and Chucky would have been a legitimate threat, maybe with him trying to brainwash the other patients into 'worshipping' him and letting Nica take the blame. It would have worked well, and fit with the title of the film.
...instead we get multiple Chuckies (and one Tiffany doll, I guess) forming a "cult" with an incredibly flimsy and vague explanation that just left me more confused than it needed to and making me wonder as to why Don Mancini felt the need to do this bizarre storyline. It sucked out any kind of creepy vibe the movie had going for it. It was so...off-the-wall bonkers, and that's saying something given Bride and Seed.
And don't get me started about Andy. What the hell was his
purpose in this movie? Heck, the synopsis made him out to be a major player in this, and with his original actor coming back, you would
think he'd try to, like, help out Nica and maybe try to clear her name. Which he sort of tries to do in Cult, but it's not focused on much. Heck, the movie even
starts off with him, yet he barely plays into the plot until the very end, and even then the resolution to his character makes his plotline seem all the more pointless to me. He doesn't even get to interact with any other character besides two of the Chuckies, possessed Nica, and I guess the psychologist and Tiffany (the latter briefly on the phone).
And speaking of the therapist, watching this film in around the first half hour had me hoping they wouldn't make this guy out to be a complete prick or secretly evil, like he'd be a rational well-mannered person who wouldn't believe Nica at first but after actually witnessing Chucky being sentient
without being killed off while at it, he'd help her out. But nope. He basically almost rapes Nica in many of their therapy sessions, because reasons. What's even more perplexing about it is how much Chucky was disgusted by it, and even sort of defending Nica at times, which was really out of character for him. Yeah, you tell him off, dude who used to strangle people before transfering his soul into a doll and leaving a body trail and two traumatized kids behind! Truly, you're the better person here.
The majority of the supporting cast is pretty much there to just die and that's it. When the asian chick who accused Nica of murdering the old lady and being overall nutso discovers that she was right all along...she's the first to get axed off. Of course. Heaven forbid you did something more with her. Malcolm was a character with interesting potential due to his multiple personality disorder, but they do almost nothing with it. What was the point? And what was the freaking point of him and Nica screwing each other in that one weird scene if they don't follow it up?

That was one big lipped alligator moment.
