Two of the things I miss most about reviewing theatre with greater frequency are raving about area artists whose talents I'm quite familiar with, and raving about area artists whose talents are brand-spanking-new to me. Happily, regarding the Playcrafters Barn Theatre's The Red Velvet Cake War, I get to do both. And that's especially gratifying because one of the things I absolutely do not miss is explaining why certain well-meaning, lighthearted endeavors designed solely to entertain simply don't work for me, and it looks like I have to do that, too.
