Geometric Stencil is a pretty silly typeface, but it’s hard to argue with its well-proportioned geometry. And in the right context, and the Rock of Ages posters are a good example, it can be pretty great.
Unfortunately every cheap sign and awning maker in town seems to have it as one of their six available fonts, and it gets used in places it shouldn’t. Maybe I shouldn’t blame the font, but I still think this falls under the Split Personality criteria. Sort of like that episode of Seinfeld with the two-face.
