The Assylum is proof free market doesn't work.
The economic theory assumes desire for profit and competition will make sure society will get best products possible for lowest possible prices.
As we see here (and in countless of other examples) you can still make money making crappy products, contributing nothing to society and wasting money, energy, resources, human labor..etc (along with annoying people with those products)
Defenders will surely claim that just means the system isn't 100% perfect - Ofcourse you will have crappy products once in a while.
But here we see manufacturers of crappy products keep making money over and over and over again. The market doesn't force them to change in any way.
Some will now claim that since the product made money it has to have benefited someone - someone liked it otherwise it wouldn't have made any money.
This ignores the fact the product made money to the point of financial success due to the fact it was misleading - as are movie titles ripoffs in this case. The manufacturers of this kind of products precisely count on parents confusing their movie with the original, as in other cases counting on the fact that people won't have the time or the will to check the reviews of products or be psychologically manipulated in other ways.
OK maybe i've gone too far, this can be a very long debate. I just hope you get my point.
