I fear the day comics are truely accepted as being cool and mainstream. When after years of whipping the horse far past death the creators and editors have gone so far out of their way to accomodate mainstream interests and tastes that the core of what made them enjoyable is so far gone you can't even remember what it used to look like.
I have to respectfully disagree with you! I agree with you in the sense that I want comics to remain good, and enjoyable, but I think you've fused some issues. Being mainstream or cool doesn't necessarily mean the destruction of comic quality... why, just to be difficult, I could argue it may entice more widly recognized and more expensive talent into the industry just because there is a larger market... I think Laurell K. Hamilton's working with a Marvel imprint probably has something to do with that. Dark Tower's HC success is going strong because it has a market beyond just comic fans.
But in any case, comics is a market that includes a variety of tastes-- mainstream to the l33t. So, if you want to sell well, it makes sense to match mainstream tastes with a mainstream market size, and that does little to affect the l33t taste and their books. It's just diversification of risk, which is very safe.
Anyone think Rocky Balboa was as good as the original? That's what happens when a medium is considered cool enough for every company, film producer, product marketer and PR firm is done with an industry. Now you might say, sure, but there's plenty of good movies still coming out, and that's true. But then you look at the bad to good movie ratio and see all the crap that's just blatantly pandering to an audience of third graders and look at how hard it is to get something original out there and you see just what a crappy state that industry is in.
Sorry, there are a bunch of bad comics already, to this, all I have to say is I'm concerned about absolute levels in this case-- do I care how many crappy comics there are? Well, if the market is oversaturated and it causes a crash. But I don't really care about that. I care only about this-- how many books I want to read. Speaking marginally, if we 3 to 1 on bad comics and then 4 to 1, you'd say this is a failure, but I would be fine with it-- if that one extra comic is another Astonishing X-men or Ultimates 1-2! This happened with the videogame industry. Tons of crappy games flooded the market because PS One was so easy to develop for, in contrast to the Saturn. Naturally, PS had a ton of horrible games. But it also had FF7, MGS, Tekken... you get my point. Saturn was the "hardcore" gamers system, with l33t stuff by Treasure... guess which lasted longer! I think we should all be concerned about good comics, knowing that bad comics, really bad ones will be done away with! The good thing about a reasonably established market is that the fat gets cut. And why can't third-graders have their movies? When you were in third-grade I bet you wanted something G or PG rated. I know I did. And I thank my mom for taking me to see them!
I like comics as uncool, I like creators able to take risks because it's not a multimillion dollar possible mistake every issue. I don't mind being a bit of an outcast for liking comics, makes you a little more interesting IMO when you don't follow american idol or know exactely what angelina jolie had for breakfast that morning and you indulge in something "different". Currently comic concepts might be cool but comics themselves aren't as mentioned above. I sincerely hope it stays that wway.
Comics uncool or cool? Largely uncool! But this could be a critique of the fans (I'm just saying what I think the consensus is from people I know!). Can creators take risks? Well yes, there isn't any reason to believe that comics cost of production will rise. Unlike videogames, risks are still acceptable... since production values aren't really the issue. Making comics mainstream diversifies the market which is an inherently risk-diminishing strategy. All it does is increase sale outlets and reach different fan-bases, there is no reason to think that Batman will be any worse, or that Vertigo would be afraid to make any more edgy books.
