I like this video, I'll be honest, I'm not a fan of Ralph Bakshi's films. I did like what he did with Mighty Mouse, and I think he has a really nice drawing style and some great cartoony sensibilitys. But beyond that, his stuff just isn't my thing.
I do have to admit that he does make a good point in this video I don't agree with everything he says but I like the attitude in which he says it. Pixar got to be where it is today by making short films, they studied and perfected the craft of making them. And doing that got them to be where they are today. Sure theres a lot of other factors but if Pixar didn't make those shorts they'd still be making software today. A lot of good can come from a well crafted short. Go out there and make one.
