I love Absolutes but they've lost some of their luster. They were originally - or at least it appeared that way - set aside for truly special stories. Dark Knight, Watchmen, Crisis, Kingdom Come, etc.
Now they'll put anything in the form. Snyder's Batman, Smith's Green Arrow, Transmetropolitan (and yes I love this series and bought the Absolute, but it would have been better served in deluxe), etc
Don't get me wrong, I get DC's reasoning.
