Suzuki talks like a dev. It is their job to sell his vision to the masses in a way they understand. It is also their job to communicate a JAPANESE developer's thoughts in a way that an English-speaking audience can understand.
Also, Awesome Japan are just hilariously, visibly inept bozos.
Awesome Japan can only do so much with the content that has been produced. If Suzuki hasn't made much more than short, janky-looking footage of Ryo and Shenhua walking through the forest and skipping over a stream, they can't really will into existence footage that explains the purpose of all the stretch goals.
It's entirely possible that AJ told Suzuki, "Hey, you need to generate more appreciable game footage before you launch this Kickstarter" and Suzuki ignored this critique in order to meet the E3 deadline. At the same time it's entirely possible Awesome Japan were the ones rushing him to put this out before the start of E3.
At the end of the day, I don't think it really matters. This campaign was destined to be very front-loaded due to the circumstances of its reveal and the fact that it's the third game in a series of titles that had very passionate but limited followers. I can't imagine that a more organized effort would have really made a big difference.
The petition says "When i tried to get my friend to pledge his reply was: 'Why would I want to support a campaign that looks like a high school-project?'". To be fair, anyone looking up Shenmue videos on YouTube would think that the original games look like a high school project. In terms of presentation and story and voice acting, Shenmue looks like amateur hour by comparison.
