At the end of the stream you're talking about what sort of format you'd use for anime, or Kamen Rider.
IMO, the best way is just to be somewhat professional. The worst people on youtube are the fags who sit in front of a webcam and go "WOAH THIS EPISODE WAS SUPER HYPE AND BLAHBLAHBLAH"
Personally, I think the best way is to actually learn about animation or film making. If you can talk about certain techniques used in production, you look much better than the competition. I'd actually be interested in hearing about how, say, some of the old Kamen Rider special effects were done. Also, actually going and doing in depth analysis is always better than shallow analysis.
For live steams, just engage with your audience, which is something I think you're good at. I think Brent Newhalls streams are great examples of how to make streams work for anime. He sets a central question like "is it morally wrong to pirate anime" or "how would anime evolve without Ghibli" and then discusses it with his audience. This format encourages audiences to engage with you, and makes it feel like a real conversation. This is great because it taps into the whole friend simulator thing.
My two cents.
