I enjoyed this return to Wolf Creek and the crazy Australian who likes to chop up bodies and torture backpacking tourists. Now I'm familiar with the character I didn't find this as disturbing as the first film. I did feel sorry for the German couple at the beginning and I thought that they would be the central victims in the story but instead it was the Englishman and history graduate. That was a surprise, I enjoyed that part. If "enjoyed" is the right word! Sorry to everyone, if that's a spoiler!
This film belongs to the same genre as Hostel and Saw, about some evil whacko who kills because he enjoys it. Like a butcher, humans are just meat to be carved up. No sense of conscience about them. It's hard to imagine someone like that but they must exist because you read stories like it in the newspaper. The story of poor Becky Watts from Bristol in 2015, for example, in which her step brother and his girlfriend murdered her and chopped her up. An awful and harrowing story but one that was true. So these things do happen in real life.
