ITV's attempt to capture some of the Doctor Who market has been cancelled after three series. Having improved greatly over the course of it's short life, Primeval ended the third series with a pretty sizable cliffhanger which now looks unlikely to be resolved.

It appears falling viewer numbers and advertising revenue have taken their toll on the series and a last-minute attempt at funding the show through a new broadcast partner has failed leaving both the future of TV show in doubt and huge question marks over the previously announced feature film.
