It's my favourite Spaghetti too. The style is in a strange way different from every other SW.
I like films which are different, and strange is another word to describe the one or another film I like. Again, it's not a negative or derogatory term, the context is the point.
Lynch or Fellini or Greenaway are also strange and often also brillant, perfect, breathtaking etc.
But that doesn't mean that every strange film is good, some are only boring, bad, idiotic, etc.
