I would not say a rip-off, but rather a modern CG-comic adaptation of the (very old now, or perhaps "classic") dark & adult comic of Igancio Noe's The Convent of Hell.
However, it >would< be a rip-off if whomever made this adaptation tried to claim it as his own work. (because >that< is the major creative crime of Plagiarism)
