Still riding the wave of publicity following her recent MacArthur genius grant win, Jeanne Gang gets the full star treatment from Chicago’s public TV station WTTW. This documentary, “Jeanne Gang: The Sky’s the Limit,” is all praise. Blair Kamin and Stanley Tigerman figure as her head cheerleaders. It would have been nice to have someone puncture the bubble a bit, possibly interrogating Gang about architect’s limits, rather than merely presenting the discipline (and Gang as one of its leading lights) as a environmental and societal savior. The documentary does show some engaging glimpses of Studio Gang’s working methods and office style, so there’s plenty to enjoy, even for the (mild) skeptics.
