You(I) inevitably put on a different viewing hat when watching a film that has a considerable reputation. Your expectations are enhanced, you're inclined to be unforgiving, so on. Dawn of the Dead being the classic that it is, I went into it with a very judgmental hat on. Fortunately, my hat stayed on, for Dawn of the Dead lives up to its reputation. It's beautifully put together. The gore effects are quite awesome. It carries considerable emotional heft. I was especially struck by how relevant the social commentary has managed to stay. Greed, consumerism, capitalism, media influence, all that rot. Quite prescient, is what I'm saying.
The zombies themselves are interesting creations. Romero tapped into something important when he gave these creatures, who could be (and have been) portrayed as ravenous hell beasts, a mournful and misbegotten feel. The zombies in this film come across as more confused and sad than evil. Consequently, you feel sympathetic rather than disgusted. It lends a tragic human element to the proceedings, as opposed to a more nihilistic feel. Great head explosions as well.
