Either you understand and appreciate the difference between (a) low-rent horror films aimed at the sandal-wearing slovenlies and mall meanderers and (b) classy, refined upscale scaries like Personal Shopper, The Babadook, The Witch, It Follows and Roman Polanski‘s Repulsion. If so you would also appreciate the difference between Personal Shopper director Olivier Assayas and a talented but opportunistic genre whore like director James Wan, whose latest film is The Conjuring 2 (Warner Bros., 6.10). Wan directed the original The Conjuring, which I thought was fairly decent but not all that great at the end of the day. (It tried too hard, and all but destroyed itself with a happy ending.) In any event I’m down for tonight’s all-media showing of The Conjuring 2. I know what it’s going to be.
