CBS has ordered an addditional five episodes of the freshman drama Eleventh Hour, bringing the season order to 18. Eleventh Hour is based on the British series of the same name, and follows government scientist Dr. Jacob Hood (Rufus Sewell) and his FBI partner Rachel Young (Marley Shelton) as they try to stop scientific experiments gone bad.
Through seven aired episodes thus far this season, Eleventh Hour has drawn solid and consistent ratings, averaging a 7.4/13 HH rating/share, 11.36 million viewers and a 3.0/8 A18-49 rating/share. However, the problem is that the show performs poorly as a lead-out to CSI: Crime Scene Investigation, with retention levels of just 62% among households, 58% among viewers and 56% among adults 18-49.
