Katie Couric can't win, can she? Her version of the CBS Evening News is consistently criticized for being too nice, happy, and morning-show-like. But when Katie gets down to business and does a serious interview with someone, she's knocked for being inappropriately stern.

That's what Couric is facing the day after her 60 Minutes interview with presidential candidate John Edwards and his wife Elizabeth. During the interview, Couric asked the couple tough questions about whether it was wise for the Edwardses to continue on the campaign trail now that Elizabeth's cancer has metastasized and become inoperable. Instead of proceeding in her usual warm, smiling manner, Couric decided to be deadly serious, keeping a straight face and pursuing lines of questioning that started with "Some say," like when she said to the couple, "Some have suggested that you're capitalizing on this."

After CBSNews.com posted the interview and allowed viewer comments, many took Couric to task for not being understanding enough, especially given her family history (her husband died of colon cancer in 1998).
