Should I buy Alan Moore's Supreme?

Personally I'd say both Supreme and A Small Killing would fall under "nonessential Alan Moore." Supreme's a goofy, parodic romp, but done with characteristic Moore flair; A Small Killing struck me as disappointingly contrived and predictable.

I think Supreme, both books, is/are great, but you really have to love the idea exploring and messing with the history of comics, and it helps to have been reading for a long time. Like, while you can give Watchmen to someone who's never read a comic before and they'll be able to follow it, Supreme would be a mess. Remember Crisis On Infinate Earths and all that?

i think it's a delight!!

I've just read the Supreme book "Story of the Year" and while it's certainly minor ALan Moore, I can definitely also say that I've never been more impressed by Rick Vietch's art. The flashback stuff is the best drawing I've ever seen him do, and not just because it shows off his amazing ability to evoke many bygone styles of comicsry. He's also able to make each of them instantly recognizable as his own style, and inject each with an equal amount of nostalgaic affection as is in Moore's script.

the flashback stuff is great (i've just read it too)

who cares if it's "minor"? what does that even mean?

1 - It means the third degree is a minor third above the tonic

2 - It means I don't find it as elegant or thought provoking as some of his other works and am less likely to re-read it.
