Whereas for me, it's always been Star Wars: I was bored by the first one back in '77 and have remained more or less unmoved by the rest. Everyone has their blind spots. :idunno:
At the extreme other end of the entertainment spectrum, I've never much liked the films of François Truffaut (although I like his critical writing, including his great book about Hitchcock, and I even like other Nouvelle Vague directors like Godard and Rohmer).
