The latest trailer looks great to me.
The things that made WWZ great was the focus on the overall world outbreak and how people were dealing with it. However, it also had alot of stupid parts. The biggest one was Yonkers. It was cool initially but the more you think about it, the more ridiculious it gets with slow zombies. Slow stupid zombies simply arent going to be able to outflank a modern army. Talking about "fighting the last war", hell, the military in Yonkers was fighting WW1 style. I don't believe it would have worked onscreen at all.
Seeing a world outbreak with fast zombies could be quite awesome. The helicopter being pulled down I thought was chilling in the trailer.
