In the final numbers for Saturday's two hour finale of Persons Unknown, it averaged 1.58 million viewers and a 0.4with adults 18-49. Both measures were up a little versus Persons Unknown's penultimate Saturday telecast.
Some have asked whether there would be a season two. Don't get your hopes up and certainly don't hold your breath. There's really no doubt that Saturday's finale was both a season and a series finale.
