I've watched the 2-part pilot. It's okay, but it could be better. I'm not a fan of Flash animation, and the show is pretty half-hearted in its attempts to maintain the original's educational aspects, with just a few throwaway references to geography. And it has some problematical elements in its portrayal of international cultures. For one thing, what the hell is a diamond called the Eye of Vishnu, after a Hindu deity from India, doing in an archaeological dig in Casablanca, a city in West Africa?
I also wasn't fond of the blatantly stereotyped portrayal of the instructor Shadow-san. Western shows that depict Japanese people tend to steep them in traditionalism, in pure Japanese attire and trappings without a shred of anything Western, but in reality, Japan has been a heavily Westernized culture for the past century and a half. Japanese people mainly only dress in kimonos and traditional attire like that on certain holidays and formal events, at least going by the Japanese TV and movies I watch. So this is sort of like if the French Interpol officer had been dressed up in Napoleonic-era cosplay instead of a modern suit and coat. Also, since he's a teacher, he would more properly be called Shadow-sensei. Calling him Shadow-san is like addressing a doctor as "Mister." Not to mention that it's weird to append a Japanese honorific to an English-language epithet like Shadow. The Japanese word for shadow is kage.
