More or less, zzzzz.
If you haven't read the novel, it's worth seeing. It's still good, but more or less everything good about it is based on the strength of the original. If you have read the novel, it's basically the same.
Though I am kinda glad they cut out the whole excessive Black Freighter thing, but the movie was super long and, for better or worse, didn't deviate from the graphic novel much at all. It's a nice, if somewhat tediously long, bonus for those of us that have read and enjoyed the original. I think they made it way more violent though =/ or at least more noticeably violent. I did laugh when they were calling Veidt (Veldt? Can't remember off the top of my head. Ozymandias, at any rate) a socialist, though.
And WTF version of "Hallelujah" was that? I guess I'll have to go with "the worst version ever."
