I think sometimes people miss the point of these films...
...they are meant to be absurd beyond absurd. They are in fact meant to be more comedic than serious.
They deliberately create characters you will hate so that you enjoy watching them die (and target the most detestable people in society), such as big tatted and titted bimbos and mimbos so you will thoroughly enjoy the carnage.
These kinds of films usually have some level of a cult following and are made all the more hilarious by seeing who pops up in them and how elaborately people are killed.
Not to be taken seriously people, just to be enjoyed.
I love it!
