Very nice!
I like the style! I don't think I've seen it anywhere else on Newgrounds! Although, for some reason it reminded me of Sesame Street even though Sesame Street didn't do anything like this. I think it was just that you used kids. By the way, are you in Britain? I just noticed that the kids had very pronounced accents.
Anyway, nice smooth animation that went well with what the kids were saying. For unrehearsed interviews, you got some marvelous answers although I doubt those boys did asking their teacher when art was invented. Anyway, nice intervies and I don't know what you're talking about 'averagey' film and wasted money. An HD camera is never a waste of money as long and you continue using it and the film was lovely!
Anyway, 5/5 and 10/10. Beautiful job.
