Everything is in place for what really ought to have been a deeply scary, even deliriously entertaining visit back to midcareer Shepard-land. We have Tony winner Nina Arianda as an impossibly slinky, outrageously bold May and Sam Rockwell as a dirt-kicking Eddie who makes the most out of cleaning his rifle and can lasso a cheap dinette chair until you almost feel sorry for it. In fact, Rockwell doesn't just rope the furniture in director Daniel Aukin's hardworking physical production. The actor, who has clearly been practicing, also lassos Arianda...Although Arianda and Rockwell have the looks, the presence and the guts, there isn't the down-and-dirty chemistry that makes the fate of the lovers' long and conflicted relationship feel inevitable and dangerous...Suffice it to say that the violence feels phony and it's hard to get overheated about the fate of the characters.
