Ok, I have an argument that I think I can actually back up and write a paper on, etc. Ahem...
Claim: Disney's specialized output has lost its ability to innovate
Reason: Because Disney's specialized output caters to a very conservative, easily angered group.
Assumption: Whatever caters to a very conservative, easily angered group loses its ability to innovate.
Audience: I am writing to the people who always want Disney to try new and progressive things, like adding homosexual couples to fairy tales. Disney cannot be that progressive, because it is playing to perhaps the scariest audience in the world-over-protective parents. Let's face it-kids watch Disney. Why? Because their parents trust it to be as nice and not-indoctrinating, and warm-fuzzy as possible. If Disney suddenly came out with an R-rated movie, no one would ever watch it.
Aha! Now for a preemptive strike by showing that I know all the counter-arguments that will be raised against me:
Parents are criticizing Disney for being too Conservative. Their first black princess came out less than a year ago! Parents aren't complaining about that. They are complaining about old stereotypes that Disney has not changed since 1937. Pixar is new and progressive, and they aren't getting angry parent's picketing. Disney's specialized output should help it to innovate. They don't have to worry about pushing a language or violence barrier, so they can focus on social commentary. Knowing your audience helps you talk to them better. What do you mean that parents are conservative and easily angered?
