TWO GIRLS AND A GUY doesn't waste any time making its points, and therefore results in an entertaining, if somewhat shallow, 90 minutes of sharp dialogue and intrigue. In the wrong hands, this film could have easily digressed into a tiresome succession of arguments or a psuedo-intellectual piece of pornography, but director James Toback handles the material simply and straightforwardly. The real star of the production, however, is Robert Downey Jr, who delivers a loose, inspired performance that captures the absurdity and hidden demons of his character. BLAKE ALLEN isn't likeable or even admirable, but he's got a certain charm. And you can't help but sympathize with him at the film's somber conclusion....
