TABOO became a controversial hit when it was originally released so it was a no-brainer that a sequel would eventually follow.
The first film, I'd argue, got lucky and it actually turned out to be a decent film but this sequel isn't nearly as good or as entertaining.
Obviously the producers knew that they had to do something more shocking than the first film so now they have a guy trying to break two different taboos.
Not only does he go after his sister but there's also the mother.
If you're just into the sex scenes then there are plenty of them offered up here for your entertainment. I do think the original TABOO wanted to tell a story and try to be something more than just your average porn film.
