I haven't seen DotD, but I love 28 Days Later, with both endings!
I thought it got better towards the end, not worse. How odd... I found it more a thinky movie than a scary movie, about the possibilities of outbreak and the resulting apocalypse. Oh well.
I even downloaded some of the songs from the movie. They're about 10 minutes long each, but they really set the mood.
Godspeed You Black Emporer is the band.
