Don't like the film, or what's the problem with A patch of Blue?
I included "A bite to eat, because as I wrote somewhere else, the short works as a perfect "naturalist" prologue to the film, that inhances the suspense of "Diamonds of the night" and is a great contrast to the latters surrealist and rather "loose" form. I think they fit together perfectly. Do you mean you saw "A bite to eat", or did your copy of "Diamonds of the night" have german subs?
Yes, 1967 seems very strong. It's almost like 1967/68 was a culmination point in cinema history. 

And I haven't seen 45 films from your list, including the largest part of american films you listed.
