I'd watch it, because some shit would be likely to get blown up real good...
But I was rereading Ellis' Authority run the other day, and it struck me then as it hadn't when I was a kid--it really isn't all that good. The characters are jerks, of course--but in retrospect the jerky dialogue often isn't even that witty. It doesn't help that every character's voice sounds like, well, Warren Ellis.
Only the Sliding Albion story had any real meat to it, with a decent, intriguing monster of a villain who has some plausible motivation and an interestingly dastardly plan. Kaizen Gammorah was okay, but nothing special, and basically admits to having no real motivation, and "God" was probably one the most underwhelming antagonists in comic book history, being basically a slightly badder-ass version of the Justice League's Starro. And, hell, Grant Morrison had, iirc, already done Starro in his JLA run by this point. Tellingly, in that two-part tale of an alien invasion by a goofy-looking cosmozoan, Morrison did not focus on Starro.
But the Sliding Albion arc was the one where there's a bit where the Doctor (presumably) kills like thirty or forty million civilians on Earth-Blue's Italy, basically as an act of terrorism--after the main villain has already been cut in half in a confusing, weird panel by the usually great Bryan Hitch.
I know the Authority are assholes, but that seemed a bit over-the-top even for them, particularly when nobody even comments negatively on the mass murder that didn't have a particularly pressing rationale behind it. Sure, the Engineer vaguely complains, but it's more along the lines of "wow, did we have the right to remake this planet's society?" Well, sure you did, but the tactics you chose probably resulted in about one million times as many deaths as necessary.
Again, this was the good story.
As an aside, the comic probably should've been called The Carrier, inasmuch as the Authority solved most of their problems with their ship.
The Millar/Quitely run, of course, was just plain ugly.
