Syfy‘s lighthearted dramedy Eureka has been renewed for a fifth season.

The show is currently airing its fourth season, which premiered with a time travel episode that cleverly altered several aspects of the modern-day status quo. Battlestar Galactica‘s James Callis also joined the cast this season, further helping to freshen up the show. The alternate timeline story has gone a long way toward keeping the show — about the bemused sheriff of a scientifically-advanced town — from growing stale.
