Recently, more and more Netflix original series (anime) pop up in my feed and so far, all of them are of extremely high quality. This goes in audio, visuals and usually story as well. Most of them are fairly unique compared to the mainstream ones.
So what I am curious about is if these are different from normal series. Like, do they have limitations for publication? For example, most series in Japan are for Japan only and are only able to leave the country through shipping DVDs or illegal streaming services. Is a Netflix original basically the same without any limits for publication?
What about production costs? Are those covered by Netflix and is the cast for example appointed by Netflix or does Netflix maybe have their own teams behind the shows?
Normally I wouldn't be bothered by this, but I have noticed a significant difference in quality from the big hits in Japan and Netflix original series. For example, most shows tend to forget about background characters, surround audio etc. In Netflix originals, I have yet to encounter these minor quality flaws. So what is it that makes the major difference between them?
I do am aware that legally the Netflix originals can only be found on Netflix. Does this mean that Netflix might be a new competitor in the anime industry?
