The Panic of ’29 isn’t deep. It hasn’t much on its mind, except camp silliness and an encyclopedic knowledge of old-movie tropes, mixed up and scrambled and spilled out on the modest 59e59 stage. Graham Techler’s loose comedy is a Less Than Rent production, which claims in the program that its mission is “examining the relationship we have to capital and the web of injustices that stem from an allegiance to profits over people.” We don’t get a whole lot of that, except in the broadest terms, but we do get some zingy one-liners and a lively troupe of players. The first half-hour or so of The Panic of ’29 is rather delightful. And then it just goes no-damn-where.
