the one kristen stewart was supposed to be in? forget the gore, the subject itself is so not pg-13...
some i like for style, others for substance. Others simply have a filmography i have enjoyed the whole way through. off the top of my head:
Coen bros
David Lynch
Denis Villenueve
Michael Haneke
Cary Fukunaga
Nicolas Winding Refn
Jacques Audiard
Quentin Tarantino
guilty pleasure/pain: Lars von Trier
edit: forgot Terrence Mallick
