This was one of those shows I saw advertised on skyone and gave it a miss when it was originally aired (although I love that kind of thing) because it seemed like another x-men rip off and until Heroes those kind of shows werent great.
But a few years later I decided to set my skybox to record them all each day when repeated and I've come to really like it and realised how well written it actually was.
Its not just another special effects ridden tv show about people with abilities! Its far more about the emotional impact of those abilities on the people, the families the world and the two agents sent to watch them.
I would reccomend watching all these before buying them to make sure you like it, as its bound to be repeated on skyone again at some point, but personally I think this is going on my xmas list this year.
Im glad I waited for the entire thing to be out in a box set.
