Dir/scr: Quentin Tarantino. USA 2007. 115 mins. Quentin Tarantino should go back to making films that matter. If the shorter, Grindhouse version of Death Proof, his hybrid slasher meets car chase homage to early 1970s B-movies, hinted that everyone's favourite cult director was running out of creative gas, the full-length Cannes edit leaves no shadow of a doubt.
