Last week while gearing up for Halloween I watched all of Romero's Dead movies. For me, Night and Dawn worked better, not only because they are the superior entries, but because they came earlier in the Dead timeline.
As the series progressed, the dead became more obviously dead. It was scarier when they were freshly reanimated at the beginning of the event.
Diary went back to the roots, and so far all the images from ...Of The Dead appear to also.Bring out your dead, George, we're ready to be scared again.
