As most reviews have acknowledged, the best thing about this film is the practical FX.

The family drama doesn't resonate as strongly as it could but it does build throughout the runtime. The father figure is sympathetic and a poignant "team-effort" moment at the end of the film lands surprisingly well. I didn't think they would but the characters won me over in the end, despite their flaws.

The pace is a little slow but things go hard enough in the last 20minutes to be worth the build up. Not only are the practical FX well produced but the way they are revealed to the audience, first in close-up, then in low light, before being shown in full glory is just fantastic.

Recommended for fans of When Evil Lurks (2023), Almost Human (2013) and Altered (2006).

Sparse, confusing plot. Thoroughly unlikable cast for the most part.

Dreary and derivative to the extreme.

The most of the creature effects seemed like they were practical and well-made. I also thought the one garage employee was a perfectly serviceable character. Haha, serviceable...get it? Get it!?

But the three brothers and whatever they were doing on screen just wasn't my bag.

And if the "disorder" of the title was supposed to be some metaphor of an affliction of ageing, that didn't work at all in the slightest one bit remotely to any extent by any means.

I don't even think knowing what was going on would make the film enjoyable. Nor does it need a sequel.
