Tavernier, no (because formally uninteresting, although i do like CAPITAINE CONAN). Armstrong, no...but for no better reason than the one you suggested: okay films, nothing terrific. Perhaps Verhoeven, Breillat, Ruiz, Romero, and Kluge? And while I'm feeling playful, how about Frank Oz? He's Yoda, he's made at least 2 good films, he's proven not to be full of Jim Henson's bollocks. :)
