'Christmas Carol' Makes It Simple By PHILIP BRANDES Santa Susana Repertory Company's child-friendly "A Christmas Carol" paints Dickens' tale in bright, bold colors that guarantee the clarity of its hopeful message. As Scrooge, Walter Koenig nails the stone-hearted miser at the outset, rebuffing the overtures of others with self-satisfied sneers. The apparitions are a mixed bag: Lane Davies is a regal Christmas Present, deftly modulating cheeriness with more ominous undercurrents, and Ruth Cordell is a sympathetic Christmas Past. However, in Scrooge's dismissal of David Himes' over-the-top Marley as a "bit of undigested beef," ham would be nearer the mark. The menacing phantom of Christmas Future looks straight out of "Star Wars"--one of several design distractions that include dresses better suited to chorus girls and scenery from an opening park scene that becomes an obstacle course in later minimally furnished locales. Director Allan Hunt makes a superb Bob Cratchit, exerting skillfully understated guidance in his scenes with the younger performers (including Nathan Davies as Tiny Tim). Despite some added songs and dance numbers (featuring Rick Rhodes' original music), the adaptation by James Egan closely follows the text. The most significant innovation frames the story as a memory play narrated by a twinkly codger (Robert Nairn), with a surprise twist. * * * * "A Christmas Carol," Scherr Forum Theatre, Thousand Oaks Civic Arts Plaza, 2100 Thousand Oaks Blvd. Today, Tuesday and Dec. 15, 10 a.m.; Thursday, Saturday and Dec. 17, 7:30 p.m.; Sunday and Dec. 19, 2:30 p.m.; Dec. 16, 10 a.m. and 7:30 p.m.; Dec. 18, 2:30 and 7:30 p.m. $22-$25.
