Whenever a radio reviewer says a production is "challenging," I listen to see if (s)he'll follow up with, "but rewarding" or "but worth the effort." That didn't happen in one critic's recent appraisal. In fact, she went further, saying, "If you can sit through (this play) without wanting to lop your own head off, you deserve to be knighted."
If she'd posted that review on Twitter, it would likely pass for relatively mild criticism.
