It felt like it was going somewhere at first, until it started to stumble over its own concept and collapse into a ditch where it soon died and rotted away. This is an example of a movie that was too smart for its own good.

Their attempt at giving zombies "humanity" was a train-wreck. The way the scientist woman kept butting in every 5 minutes to give a pseudo-scientific explanation of everything wreaked of desperation from the writers, like they really wanted you to buy into this concept but it just ended up being laughably bad.

The only thing i appreciated was how they actually committed to creating a realistic post-apocalyptic world. This certainly isn't one of those movies where the "apocalypse" is only depicted as a burnt-out city skyline in the distance. You actually get to delve deep into a desolate zombie-infested London and the sets they created are pretty fantastic. As a Londoner myself i was impressed, it looked better than 28 Days Later.

But cool sets aren't enough to make up for bad writing. This might be worth watching if you REALLY like zombie movies. But for the average viewer it's a waste of time. There's no story here, the plot is just a boring escort mission that ends nowhere.
