DING DING-- Dollar dollar. DKR in particular I've harped on about on these very forums far too long to repeat. I can link if someone's interested in the last time I went long-winded on it, but I'll refrain.
I'll add to the agreement that Hush is overrated. It's all about the Jim Lee art and everything else is pretty shallow. I liked it when I was younger but it hasn't aged well.
The Batman/Superman fight is pretty solid, though. I think both come out fairly, although Bruce gets very melodramatic in his monologue.
They're both a bit clumsy with the argument about the slippery slope and I think that 775 comes dangerously close to actually broaching a better foothold (how terrifying Clark can be if he just decided might makes the rules and why he personally needs to have heavy checks and balances in his line of work) but is too in love with the idea of Superman as a symbol for altruism that it forgets him as a character. Still it's an earnest attempt, but as with most stories asking "do we need a Superman," they're so preoccupied with the question that they trip over the answer that so many others have illustrated with him simply being himself. That one page from All-Star does a better job showing why the world needs him than all the naval gazing we've done since 1986.
But 775 specifically tries to take a moral stance over what we all know is borne of business and was woven into character for that reason-- villains are profitable and this is a perpetual story engine. Yes, Clark can have his justifications but the minute you're kicking your feet up and saying "got 'em, chief" you probably stepped in it.
Again, it's earnest so I don't try to **** on it too much. They really wanted to have Clark plant his feet and have a moral win over Manchester but it was clumsily handled. Honestly, he'd be more respectable if he opened with "peer pressuring anyone into taking a life is wrong and that you're so preoccupied with manufacturing a system in which I'm driven to taking lives shows that you're not fit to be a moral authority to anyone. I'm taking you down. You'll not be martyred nor will you start a revolution. You're getting locked away where your ideas will wither along with your relevance, Manchester. Now square up, I don't have all day."
Instead he waxed philosophical as a mic drop and peaced before he could hear a rebuttal; like Bruce in DKR, frankly. Beats up on his foe, says his peace and leaves the fight before he got wrecked because he absolutely would have been if the other brought their A-Game.
