Does cancellation spur creativity?

As Stargate Universe wraps its two year run tonight, I wonder if the reality of cancellation has provided a spark creative output from its showrunners.  After a dismal first season with unlikeable characters and boring plots, the show started its second season on a bubble, but found its creative footing.  With the announcement of its cancellation, the creative team started rehabilitated its characters and finally drew me in with its storylines.  Looking forward to see if the strong writing lasts until the end.
