I just finished watching the first episode of Dead Set, a British TV mini-series that is basically Big Brother meets 28 Days Later, and it is very good. I love 28 Days Later, and the American version of Big Brother used to be a guilty addiction of mine, so this should be right up my alley, but I think it would work for any zombie-horror fans.
The premise is that a zombie outbreak takes place outside of the Big Brother set, so that the contestants inside end up surrounded by zombies with no knowledge (until the end of the first episode) of what has occurred. The camera style is cinema-verite, and the grainy, washed-out look and British setting makes it all look very 28 Days Later-ish. There are to be five episodes, leading up to the finale on Halloween; and, as they were written by Charlie Brooker (who is known for surreal satire), it should end up with some biting commentary on the way reality television deadens culture. That said, this first episode had little of that, and was just spot-on effective horror. So watch it if you're in Britain and get the E4 channel, or torrent it like those of us who aren't and don't.
