"Some" is not "peremptory'', final, total, definitive (once and for all) and categorical.
"Any" is all that.Any is also used with not in negative statements. In these statements, the word "any" emphasizes the negation. It can be left out to soften the negation.http://www.edufind.com/english-grammar/ ... uantities/
Let´s say that in "They don´t like some kind of movies" (is softened by "some kind", that is, they like other types then.)
They don´t like any kind of movies. (there is, it´s conclusive, they don´t like "any". No kind, definitely none.)
