4 Another great season.DaveFaz | 29/03/2008 | See all DaveFaz's reviews (182)Top 100 Reviewer Top 10 DVD Reviewer Top 100 PC Reviewer The season starts, predictably, with another terrorist threat that will imminently wipe out millions of lives. The first half dozen or so episodes on the season are the weakest as far as the story goes. Some new characters are introduced and roles changed to keep existing characters in the series. That's all reasonably believable, but the writers try to surprise us with an earth shaking twist that goes a little too far. Once you enter the realm of "anything can happen" you start to wonder what's the point in watching, it may all turn out to be a dream anyway! After that, though, the story settles down and progresses well, with enough depth to it so that it remains interesting all the way through. And with enough tension to keep you glued to the screen. It's fast paced, with superb acting from Sutherland, and strong support from the other others. All in all, highly recommended viewing.
