Maybe I'm mellowing out as I get older. Back when Kingdom Come originally came out, I was a big fan of Magog. I liked his ridiculous look, I liked his "rebellious" attitude towards the older heroes, and I liked that he killed the Joker in that alternate history story. But now that we have Magog showing up in the current DCU, I think he's kind of a jerk.
Keith Giffen does a nice job fleshing out David Reid/Magog in the first issue. Magog knows who he is, at least. He knows he's a hard-edged hero that will do more than what other heroes will do, both morally and politically. I admire the self-awareness he shows when he comments that he knows there is no way he can last in the JSA. He also lies to Alan Scott about trying not to kill people, another funny bit showing that Magog knows exactly what kind of hero he is. My problem is how dismissive Magog seems to be towards the attitudes of other heroes. He makes a few comments about still respecting GL, but not enough. The core plot involves someone selling low-end meta tech to criminals around the world, sort of a low-tech Intergang. The concept is ok, but the book needs a real antagonist fast or I'm afraid I will lose interest.
Howard Porter sure enjoys drawing teeth breaking. Twice in the first issue Magog busts up someone's dental work, and then we have 3 or 4 guys getting their skin blasted off too. I think I'd prefer a more "comicy" take on Magog's energy blasts. With his beams looking like they are searing folks to death, Magog comes off as a bit of a sadist.
