The fifth season, which concluded with "The Big One" Sunday night (Dec. 12), averaged more than 5 million viewers per week, making it the series' highest-rated season to date.
The finale itself nabbed 2.9 million viewers from the 9 p.m. (2.5 million) and 11 p.m. (401,000) airings combined. This is on par with the series' stellar Season 4 finale and a good 40 percent up from the premiere's 1.77 million viewers.
When all is said and done and watched On Demand/Live+7, the Season 5 finale could boast as many as 6 million viewers.
In "The Big One," Dexter (Michael C. Hall) concludes his search for Lumen (Julia Stiles) , who's been kidnapped by Jordan, the leader of a group of men who raped, tortured and killed women, known to the Miami Metro as the Barrel Girls.
