Evil Old Irish Grandfather

As far as I know, there has never been an evil old Irish grandfather figure. Why is that?

Hell, the Irish are seriously lacking in the villainous departments. Canadians, too, for that matter.

I mean, the Irish have leprechauns. What do Canadians have? Biker gangs? Pshh.

How do Leprechaun get 5 sequels?

Did the story of Leprechaun really need to be told in 5 parts?
What could the remaining 4 need to say that could not be said in the first Leprechaun series?

Peace out.
