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.

I wish I knew why I still pay for Shudder. Very little new content is added and when it is, it is either "Shudder exclusive" nonsense like this and In A Violent Nature or a "Shudder Original " like...well, name any Shudder Original, they pretty much all stink. This one is yet another average possession film, with the distinction of Australian accents. Shudder was much better before it was under the dubious wing of AMC. At least then there was the possibility of finding an older classic to revisit. Now? Not so much, plus all the new stuff absolutely suck. Skip this, and skip Shudder if that's at all possible.

I usually don't like horror movies anymore as they are mostly boring to me. And the lot of them are so low budget that the acting and special effect are horrible.

But I believe in time, that this low budget Australian gem will become a cult classic.

I thoroughly enjoyed this movie from beginning to end!! The acting was pretty decent and the low budget special effects were amazingly gruesome.

On several occasions I caught myself yelling "Ewwww" out loud followed by a laugh of disbelief at what I had just watched!!! I gave it a 7 out of 10 for the type of genre it represented, but this movie definitely gets a 10 out of 10 on the gross scale with a commendation for its large "Ewwww" factor.

I would recommend this for anyone who likes this genre. As it never really had a dull moment, it keeps you on the edge of your seat and it's truly entertaining.
