I collected comics then as a young man that I still find entertaining today. But the comics of today just plain leave me cold and I do not collect any. I have not 'outgrown' comics, comics have 'outgrown' me. There must be many others who feel the same way.
Kid Robson has made a really good point over on his blog, that I wish the industry would take to heart:
"Simply give the potential readership what it's crying out for - good, old-fashioned, entertaining stories that diverts attention from the harsh realities of life and takes the reader on a rip-roaring, magic-carpet ride into worlds of fantasy and enchantment."
When quality comics are created for the young at heart, everyone wins. When they are created as dark and gritty, full of hyper angst, the audience drops off to the point of harming the industry. I say look to the past and aim for the future.
