Urban Underground Media performs two actual scripts from Norman Lear’s 1970s sitcom, originally intended to provide a sympathetic, realistic portrayal of a poor black family living in a Chicago housing project but best remembered for the idiotic catchphrase “Dy-no-mite!” An ostensible spoof of Good Times might be expected to skewer the original’s schizophrenic depiction of African-Americans–sometimes fair and sensitive, other times pure minstrelsy. Or at least make fun of the dated material: 70s fashions, Billy Dee Williams references. But this company has made the powerfully unfunny decision to play the scripts straight, offering little more than a Good Times rerun. Through 3/25: Thu 7 PM, Fri-Sat 11 PM, Sun 3 PM, Theatre Building Chicago, 1225 W. Belmont, 773-327-5252, $15.
