CJ’s review published on Letterboxd:
Fiona Dourif reprises her role as Nica from Curse of Chucky and this time she's been placed in an asylum. The courts have ruled her insane and she's diagnosed schizophrenic, with police blaming her for all the murders and assuming "Chucky" is a manifestation of her guilt. Her doctor (Michael Therriault) may be a little on the unorthodox and unethical side when it comes to his techniques (!) but he places Nica in a medium-security ward with a focus on group therapy and, together with her newfound mental illness buddies, they try to work out their problems with the aid of, umm... a doll... What could go wrong?
Where Cult of Chucky fails is in its attempts to tie together as many of the disparate threads as possible from the first six films. They were so wildly different in tone and this clash just doesn't work when you've got Alex Vincent from the comparatively gritty Child's Play returning alongside Jennifer Tilly playing Jennifer Tilly from the comedic meta-mess Seed Of Chucky. But, lofty ambitions aside, the main storyline mostly plays well.
It's really nicely shot and there are some great gore FX but what holds together even the roughest, weirdest, most incomprehensible parts is Fiona Dourif. She delivers an intense, genuinely brilliant performance (especially in the very final act) and if it doesn't make people wise up and her hire for more work, then I don't know what will. I mean, she can turn some of this nonsense into gold. She is a cinematic alchemist.
So yeah, it's not perfect. But it's never a difficult watch and even the missteps are so bizarre that at least they're not boring. It's not a high bar but I reckon this is probably the best Chucky film since the original Child's Play.
