I shouldn't really be surprised when I see that, yet again, the Mail has decided to go for it's own brand of pointless, idiotic, crappily written and badly researched journalism.
But it's Alan Moore. When you try and explain him to people who don't read comics you generally have to lead with the terms genius, eccentric, brilliant writer, great bloke, wizard (repeat the eccentric part here perhaps). But you always try to emphasise the general decency and genius-ness of the man.
The Daily Mail comes along and basically tries to imply he's some sort of penniless weirdo who dares to think he's above taking money that Hollywood has offered him. I know I should expect no more. But just occasionally I'd like to be surprised by them. But I'm not holding my breath.
