For what it's worth, the just released DVD/Blu-ray is advertised as
the "unrated director's cut". Until Video Watchdog gives it the full
treatment, I'm not even sure what "uncut" means in this situation
since a lot of people are referencing a festival screening cut that
might not have been a finished version to begin with. The version I
saw was "cut" but it sure looked seamless.
You might want to rethink that streaming version though, since it
utilizes something called Social Cinema and according to Dread
Central, "Social Cinema allows users to interact with the film by
sharing clips and quotes with friends. We can certainly think of
several scenes from The Human Centipede 2 that are share-worthy."
Think of the fun you can have,
