Netflix (NASDAQ:NFLX) has turned to a serial killer to bolster its competitive advantage against streaming rivals, Fool contributor Tim Beyers says in the following video.

Specifically, Netflix has signed a deal with CBS (NYSE:CBS) unit Showtime to bring the first four seasons of Dexter to subscribers by Halloween, with the final four installments available after the new year. The arrangement must be reassuring for Showtime president David Nivens, who recently said Michael C. Hall's killer of killers was as important to his network as Spider-Man is to Sony.

For Netflix, getting Dexter means more chances to boost already-soaring engagement figures. Subscribers tend to watch 93 minutes per day, BTIG analyst Richard Greenfield said in a recent CNBC interview, nearly on par with Netflix's broadcast counterparts.

Should investors expect Netflix stock to rally on this deal and others like it? Tim answers this question and more in the video. Please watch now and then leave a comment to let us know where you stand.
