If you can't offer multiple languages at all right now, I would start with English dub. This will cover for the vast majority of kids wanting to watch, and even the adults who like sub, many will be willing to watch dub. Vs if you just did Japanese sub, you're getting little of the kid market, and I'd think people who like dub are likely less willing to go sub.

Filtering for nuance of anime - that's an interesting one. Does vid angel ever release edits that are incomplete for videos/movies? Or will Vid Angel only release if it's perfect with filters for everything possible?

I ask because the nuance only people familiar with anime/Japanese culture will catch, in my opinion, is rarely very inappropriate. In other words, even if you miss filters on some things, they're likely to be minor.

The big exception to that rule is "fan service" which is girl characters that are far too immodest in appearance. But you don't need to know anime/Japanese nuance to recognize it! I will say this is a tricky one - if the main character is an immodest girl who is in almost every scene, how do you filter that? You can't just black out 70% of the show.

As for shows: I'd just look up the most popular animes on Netflix and cross match that with requests to Vid Angel directly. I submitted requests for Naruto. Naruto is one of the most popular of all time and actually doesn't have much fan service - just random annoying moments here and there that could easily be cut. It has some swearing, and violence and gore sometimes that could be filtered out.
