Firstly, forget any connection Torchwood may have with Doctor Who. This five-part mini series, which comprises Season 3 of Torchwood, stands alone on its own merit: and handsomely too. Unexpectedly, all the children in the world suddenly freeze and begin chanting the ominous words "We are coming..." - over the next five days, a sequence of events unfolds which results in the government having to confront the consequences of previous cover-ups and embark on a course which not only threatens the members of Torchwood, but every family in the country and the break-up of society as we know it. Combining a tremendously bold, thought-provoking and emotional script, a gripping storyline including a malevolent alien race who are never quite in full view and some tremendous perfromances from John Barrowman, Eve Myles, Gareth David-Lloyd, Peter Capaldi and Nicholas Farrell this is not only British sci-fi at its best - at times reminiscent of Quatermass, but with more depth and more thought-provoking - this ranks with any sci-fi programme produced in the last fifty years. Beautifully photographed and featuring an excellent heart-thumping score by Ben Foster, the series could have been made for Blu-Ray. If this is the end of Torchwood, as has been rumoured, it's a hell of a swansong. But it would be a shame - for this feels like a series that has finally lived up to its promise and hit its stride.
