I love the notion of comics, I'm just a real critical person.
As a result, most comics podcasts, like IGN's or iFanboy's or whatever strike me as very irritating in their, um, ****-eating attitudes. (sorry)
The best I've found are
'Funnybook Babylon' (though they have very few new episodes, and occasionally dive into stuff waaay before my time that leaves me behind a bit, when they're talking about something you know they're incredible.
and recently some TCJ guy's 'Comic Books Are Burning in Hell,' which is great until they start referencing very obscure things (as if I'm stupid to not have read the Smithsonian collection of Sunday strips from the 20's).
I also enjoy Gillen's 'Decompressed,' less because it's critical (it's not), and more because Gillen is my favorite.
Any others I should check out?
