This walking dead show isn't bad. It does use old school style zombie gore. Not the real fancy shot you see in new zOmbie flicks

Boyle used some simmilar shooting techniques to Romero on 28 days later, the only difference was he made his dead fast and gave the audience an explanation for them being there right away. The original dead films were shot on 35mm with shoestring budgets. Todays remakes are big studio cashed up HD and are good films as well in thier own right.
The remakes of Day and more so Dead have that new style of fast paced cuts and plenty of them combined with the faster dead, they sure still follow the formula storywise but your right the $$ thrown into them make them more graphic.
