Showtime has announced that their killer hit (har har) Dexter will be returning for at least two more seasons of brilliant mayhem. With a viewership increase of at least 16% since last season, the currently-airing third season is making the series more popular than ever. The newly ordered seasons four and five will have twelve episodes each (the usual for Dexter), and the fourth season is set to begin shooting in the spring.
