That cat is out of the bag as far as the Los Angeles Times is concerned. Animated films are coming out thick, fast, and too close together for the market to bear. Box office grosses are down, and large studios like DreamWorks are starting to feel the pinch (although they claim that Turbo will be profitable in the end.)
The problem of course isn't so much that there are too many animated films, rather it's that there are simply too many of the same kind of animated films.
Pixar set the gold standard with kid-friendly films that had more than a wink and a nod to the adults in the audience. The world and his dog took notice, and started to crank out facsimiles en masse.
Unfortunately, the market can only ever support so many of the same kinds of films. If you want a cautionary tale, just look to the Western. Hollywood flamed out on them 40 years ago, and they've been a tough sell ever since.
Animated films face the same problem today. The concern is that animation continues to be treated like a genre (even though it isn't) and guilt by association could hinder adult-oriented animated films if the kid-friendly ones overstay their welcome.
So what kind of animated films should we be seeing if we are to avoid this fate?
High school comedies? Sure, why not. Action films? That ones easy, we just need to re-classify a few that are already out there from live-action to animation. Family dramas? Absolutely! The Incredibles could easily count if it had a few bad words in it, right? I mean c'mon, it already had the whole infidelity angle going for it.
The point is that animated films that adults will enjoy and animated films suitable for adults are not mutually exclusive. It's tough to get a kid to watch a courtroom drama because it's simply not interesting to them.
There's no reason why there isn't more diversity in animated films besides studio's reluctance to embrace them, and a mentality that the juvenile approach is the best way to attract the 18-34 demographic.
The only obstacle is grabbing the headlines away from what's out there today. News organisations cannot resist falling over themselves for the latest kid-friendly animated film but won't touch one for adults with a 10 foot pole. If we can get over that, maybe we can start to see greater variety in animated form at the cinema.
