Emotionally, this must be the best documentary of the year for me. It's a very touching story, and tinged with sadness, but you get to listen to so much of that wonderful Motown music, and you feel a considerably heightened nostalgia for it now that so much less musical and less winning stuff has come down the pipe since then. I took this music for granted at the time. Now it seems incredibly catchy and memorable. How on earth did they do it? We ordinary mortals will never really know, but the secret lies in that "pit" where those forgotten men worked as a brilliant team hour after hour and made Smokey and Stevie and Marvin and the rest sound so good.
