Making a silk purse from a sow’s ear. That’s what director/ choreographer Ann Nieman and her talented cast and crew are doing in the Circa '21 Dinner Playhouse's Seven Brides for Seven Brothers, but why on Earth anyone would try to rehabilitate this porker is quite beyond me. Don’t get me wrong, though: At evening's end, I, along with seemingly every other patron in the house for the July 20 preview, heartily applauded during the curtain call. Even though I think the material is awful, the production itself is very good.
