Japan as a country is reponsible for the WWII wrong doing. The young generation should be taught the right history. They should be ashame of their WWII wrong doings. If Japan apologizes sinceerely and pay compensation for their wrong doings, it is doing them a favour. China has been one of the world leaders for thousands of years. China is emerging as a super power once again. Justice will be served sooner or later, one way or the other. Whatever you think doesn't matter. What most of the Chinese think will matter. We will set the standard. It is as simple as that.
I don't think it does matter if the WWII references were intentional or accidental. There are enough references in here to make it offensive, even if it was unintended. I'm offended by it, and I'm not even Chinese.
