I know it's not quite as cheap as the £12 box set posted the other day, but I figured there must be some people who wanted it that don't live near an HMV outlet store :)
I've never seen it myself, but IMDB give it a 7.2, so I assume it's got some good stuff going for it :)
That, and the fact that it's yet to be cancelled.
(Though that is of course not necessarily a measure for how good a show is.)
"Primeval is a rip-roaring, special effects-laden thriller in which the past, the present and the future collide. When evolutionary zoologist Nick Cutter discovers prehistoric creatures alive and well in the present day the natural world is turned on its head and humanity faces a threat to its very existence. Unexplained anomalies are ripping holes in the fabric of time, allowing creatures from the past, and the future, to roam the modern world. Suddenly the world we thought we understood has changed. Nothing is certain. What kinds of relationships emerge in this shared world of secrets and suspense? What sort of creature can you next expect to see? Where will the next anomaly appear and what on earth will come out of it? So many questions but only one thing is sure; in Primeval the past and the future are as real as the present and they're just an anomaly away. Includes all the episodes the show's first, second and third series."
