“You Can’t Have It” (* out of four). Nor do you want it. Static melodrama set entirely in one bar in which a barfly (Matthew Pohlkamp) converses with the other annoying patrons on the last night a bar is open and sex and murder later ensue. Somehow, Armand Assante figures in this mess as a mysterious underworld figure whose also at the bar. Pretty desperate; it’s movies like these that make you feel like going to A.A.
