I really liked how this one ends. I kind of wish the series ended with that last shot. I don't want to spoil, but it is kind of haunting...in that I imagine they are the last people on earth, trying to find enjoyment in their own little corner of the world.
In my mind, Day of the Dead IS the end of the series. While I don't think it's as good as Dawn or Night, it's Citizen Kane compared to Land of the Dead and Diary of the Dead.
By the way, is that early test footage of 'From Dusk til Dawn' on here somewhere? Joe Pilato was playing the Clooney role -- it's kinda sad, because I would have loved that movie 100 percent more if Joe Pilato had been in it.
