The country singer with the tumultuous personal life

The criticism of Dr. Drew Pinsky spread on the Internet almost as quickly as news of Mindy McCready's death.

The country singer with the tumultuous personal life became the fifth cast member of his "Celebrity Rehab" series to die since appearing on the show and the third from Season 3. The previous deaths stirred up rumors of a curse and a debate about the show's helpfulness, and McCready's apparent suicide upped the pitch of the reaction.

While many noted that Drew took on hard cases, others rendered stark judgment. Singer Richard Marx on Twitter compared Pinsky to Dr. Jack Kevorkian, the so-called suicide doctor: "Same results."

Marx backed off later Monday, saying the crack went too far. But he restated his thoughts in a way that summed up much of the reaction in the first 24 hours since the 37-year-old McCready's death Sunday afternoon in Heber Springs, Ark.
