The show premiered last week to the lowest-rated in-season broadcast scripted series debut ever. Its second episode performed even worse, causing NBC to make the necessary decision to put the show to rest. Do No Harm will be replaced by episodes of Law & Order: SVU until further notice.
Do No Harm didn’t have a great marketing campaign or too many promos before its premiere so it’s no wonder the show was cancelled. NBC has been having a rough time lately, especially with dramas, so losing another one won’t help them at all.
