It’s a bouncing baby bomb: Part 1 of NBC’s high-profile Rosemary’s Baby miniseries performed surprisingly poorly in the overnight ratings. The Mother’s Day remake of the classic horror novel and 1968 film  delivered only 3.7 million viewers and a 1.1 rating among adults 18-49 across its two-hour debut. In the 9 p.m. hour, it was firmly beaten by the second half of ABC’s two-hour Once Upon a Time finale and tied by Fox’s Cosmos. In the 10 p.m. hour, Rosemary’s was edged out by both ABC’s Revenge and CBS’ The Mentalist.

Rosemary’s Baby starred Zoe Saldana in the role made famous by Mia Farrow. Though reviews were mediocre (ranking only 53 out of 100 on Metacritic), one would have expected bigger numbers, if only due to its well-known title and receiving a fair amount of promotion. Perhaps between Once being extended across 9 p.m. this week and HBO blowing up its ratings with Game of Thrones in the same hour, it was tough for a new genre program to convince viewers to flip over. Speaking of which: Did Thrones set another ratings record? That number won’t be out until later today or tomorrow.
