I generally dont bother if its had less than three seasons. Mind you long running shows are not necessarily great either. How long did Last of the Summer wine go on for? Utter ****e! 
I think from memory that there were 3 Bourne films with Matt Damon and another film with Gerrard Butler as a spin off. However there are loads of Jason Bourne books - more than 10 I think - so plenty of scope for more films or indeed an action series or two.Hmm!!
Treadstone season 2 is no longer happening after confirmation that USA Network's Jason Bourne spinoff series has been cancelled after just one season. There are a couple of main reasons behind this somewhat surprising decision, which chiefly stem from the show's ratings, and the channel's overall shift towards a different kind of programming. These two factors spelled a death-knell for Treadstone, which unsuccessfully tried to pour the international espionage-based thrills of the Bourne franchise into an episodic series.
Based on the Jason Bourne films (which in turn are based on the books by author Robert Ludlum), Treadstone season 1 is set in two different time periods. A 1973 storyline follows John Randolph Bentley (Jeremy Irvine), a CIA Operative who was captured by the KGB and put through a brainwashing program that programmed him to carry out assassinations and other missions for the Soviets. In the present-day storyline, a group of operatives who were turned into sleeper agents by the CIA's own behavior modification program, Treadstone, begin to awaken.
