Journey Into Mystery 622
I bought this because the recent X-Men 534.1 interested me in writer Kieron Gillen, and this increases my new very high opinion of him. In that X-Men comic he focussed on Magneto, doing a beautiful job of defining who he now is, where he is and what we might expect from him. In this, he does something similar for Loki, now resurrected (after dying in Siege) as a child. He makes him into a more interesting character here than I can ever recall before: brilliant, talented, very complex, powerful, with a precisely judged blend of chaotic risk-taking and genuinely cunning intelligence and planning.
