Rex's jovialness does not wear thin, but let's not forget to mention the other piece in this twisted puzzle. The torture family trope is not entirely rare within horror, we're accustomed to uncouth rustic families with an appetite for flesh living in an awfully convenient rural setting. Thus, it's rare to be taken by surprise. However, we soon learn that this disturbed unit's dynamics are much more complex than an insatiable appetite for flesh. Quite simply, Rex's hosts are far from ordinary.
This erratic ruthlessness is not just exhibited through the characters, but also through the stimulating visuals. The sporadic hyper-stylisation is temptingly inviting, from the forthright confrontational cinematography through to the foreboding soundtrack denies the viewer any chance of normality.
