I saw this flick the other day, and I love his previous zombie films, definitely one of the forefathers of zombie movies and when the film started I thought it was really going to rock.
I thought the atmosphere was awesome, I thought most of the acting was great and i liked the cast of characters and the spin on the Zombies was pretty cool.
But when the movie finished, it really really felt like it could have lived up to so much more, it was a relatively short film and the myriad of cast members felt really underused. There was just that something i couldn't put my finger on.
For me 28 Days Later still remainds the stand out zombie flick of the last 10 years or so, that movie had me shitting myself.
Oh, and i thought Pretty Boy the driver chick was hot as all hell.
