Since taking over Paramount Pictures last year, Brad Grey has cemented a reputation as the Maximilien Robespierre of studio chiefs — a guy who’s a lot better at chopping off heads and creating an atmosphere of terror than bringing about the kind of inspired changes that might lead to the bolstering of Paramount’s stock through the making of really superb films. The whispered verdict around town is that Grey is (I need to put this delicately) (a) a lightweight , (b) out of his depth, and (c) not a man of commanding insight, vision or wisdom as far as the basic building blocks are concerned. Here’s a Sunday (2.5) Laura Holson N.Y. Times piece that seems to recognize what people are saying and what may be going on in Grey’s head, but at the same time seems to equivocate here and there.
