The first Human Centipede movie had a certain novelty factor about it. It was meant to shock and it succeeded, thus making it somewhat watchable.
The second was a disgusting mess with no redeeming features and would likely be in my bottom 100 movies ever made.
This, is an odd creature.
So the antagonists from both previous movies return, but they both play different characters! In the second movie the first movie was made out to be exactly that, just a movie. In this one both the first and second are supposed to have been movies.
Still with me?
Adding an element of humor this third part is undeniably memorable but not for the right reasons. It aims to shock once again and pulls out all the stops in doing so.
Credit where credit is due, the lead takes the character and makes it his own and saves the film (To an extent). The Human Centipede III is disgusting, and there is barely a story but it has moments that are very hard to get off your mind so it at least succeeds there.
Not for the faint.
The Good:
Dieter Laser certainly makes for an interesting character with Billy Boss
The Bad:
Shock for the sake of shock
No real storyline
