GrimmIt’s over for NBC’s new dating series Ready For Love after two low-rated airings, while underrated Friday drama Grimm is getting an upgrade. Beginning April 30, Grimm will move to the Tuesday 10 PM slot, airing behind a two-hour episode of The Voice, and will remain on Tuesday through May 21. Grimm will have a two-hour Voice lead-in for two more weeks, while it is unclear what will air in the Tuesday 9 PM hour on May 14 and May 21. Grimm will be replaced in the Friday 9 PM hour by newsmagazine Dateline, which will be leading into Rock Center. It is unclear when or where (or if) the remaining episodes of Ready For Love will air. The dating reality series executive produced by Eva Longoria was originally slated to air on Sundays this midseason. When Smash crashed and burned in its Season 2 return, NBC opted to launch Ready For Love on Tuesday instead, with the show getting a plum Voice lead-in. But after a slow start, Ready For Love dropped to a 1.3/4 in adults 18-49 in its second airing this week despite a huge Voice lead-in.
