True. The inconsistent art is unfortunate. Also unfortunate is how bad DC bungled the lead up stuff. I do think the whole Libra and his Society of Villains thing wasn't well laid out well (although that possibly was the fault of the lead up). My other real problem with the series was how little Wonder Woman was used (something Morrison has owned up to).
Ultimately, it's not the best DC event ever (I much prefer One Million), I like it a lot better than what we've been getting out of either of the big two in the last several years (Annihilation withstanding).
Yeah, DC One Million was definitely superior.
Morrison threw a lot of shit in FC, but there were a lot of missed opportunities that could've made the story so much better. But it reads like a standard superhero event comic to me, with maybe a bit too much pretentious hype ("My Lord of the Rings"...oh Grant...). Then again, I only read the main mini, Resist, and the Superman tie-ins.
