That tumbling wave wave was the best thing about that trailer for me. The zombie running on the rooftop was the same thing we've all seen countless times, but that wave was horrific, even more detached as it was all arms and legs, parts we recognise as human but aren't comfortable seeing flying around so. It did also make sense, sort of, taking the physics into account. They moving quickly, in huge numbers, none of whom are in complete control of their own bodies... I think they would end up like that, and it did disturb me, so... I approve.
Plus, what it is you guys have, black friday? We've all seen the pictures.
