The Dragon Ball
franchise is easily Funimation's most important property, and the one that has brought in more money for them over the years than anything else. It's incredibly important to the company's bottom line, and so obviously they're going to milk it as much as possible. Why does Dragon Ball Z
sell SO much more than all of the other anime
they put out? Because it's mainstream. The people that buy it, predominantly, are NOT anime fans, they're the mainstream consumers that made the show such a hit.
Mainstream video consumers are not purists. They detest seeing things like film grain (however naturally it occurred), because anything that isn't "pure picture" is something that, in their minds, shouldn't be there now that everything is nice and digital and clean, and they bought a nice giant flat screen TV on which to watch it. They also hate pillar-boxing, because it's a waste of real-estate on said giant screen. They don't think about things like the show's original shape or the artists' intention, they want a pretty, clean picture to fill their screen.
Funimation tried to "fight the good fight" with the Dragon Ball Z Blu-rays and restore the show into HD properly, but despite what I'm told was an insanely laborious production process, the discs they ended up putting out were not popular. They heard over and over that this huge group that pays the bills did not like those discs, for the above reasons. No amount of "education" that Funimation might attempt will be enough to dissuade the masses from liking things that way. So, rather than continuing to spend gobs of time and money making those discs, they stopped. And that's why they're going back to what they did for the best-selling and super-popular "Orange Box" DVDs, which is filter out all the film grain, brighten the colors, and zoom them in to create a 16x9 widescreen picture. It might not be what the hardcore otaku want, but Funimation has to go where the money is.
What Japanese collectors want in a video presentation is more in line with what American anime fans want: the original picture, as created, with as little mucked around with as possible. So eventually Toei Animation
will likely do their own HD restoration and come out with their own Blu-ray boxed set in Japan. And Funimation will probably eventually release those here, too, much like they did the Dragonboxes on DVD. But it could be some years until that happens (if it happens at all), and in the mean time, I'm sure Funimation would like some more money. I certainly can't blame them.
