ABC‘s Red Widow arguably had the biggest marketing campaign of any midseason series, including plum spots during the network’s Oscar broadcast last Sunday. For all that promotional blitz, the two-hour premiere of the mob drama fell short, extending the underwhelming track record of this year’s crop of broadcast midseason replacements. Red Widow drew a 1.4/4 among adults 18-49 from 9-11 PM and 6.9 million viewers. That was down 36% from last midseason’s debut of GCB and this fall’s opener for 666 Park Avenue. Both Sunday 10 PM ABC dramas had hourlong premieres and both have been cancelled. On the bright side, Red Widow saw very little audience erosion throughout its two-hour debut, indicating a possible future cult following. Leading into Red Widow was Once Upon a Time (2.1/6), which didn’t benefit from the Oscar exposure either, down 13% from its last original two weeks ago to a series low.
