Tonight, Do No Harm, which NBC yanked after just two episodes, which earned a 0.9 and 0.7 in adults 18-49, joins the crowded Saturday burn-off field where it will face off against Zero Hour (0.3 adults 18-49 last week), 666 Park Avenue (0.5 adults 18-49 last week) and Brooklyn D.A. (0.5 adults 18-49 last week.) Yes, this week Saturday has more original programming than most of the weekdays. It’s a given that all of these shows are going to do poorly tonight, The question is which one will do the worst. The safe money seems to be on Do No Harm, which never cracked a 1.0 during its short life, but Zero Hour made a pretty strong case for itself last week. Plus, this week the Saturday shows aren’t facing the Stanley cup finals which could have impacted the ratings for other shows last week. What do you think? Make your predictions.
