I've been chugging my way through the Chinese series. It's a *lot* more faithful to the book, to the point of being set in 2007 (Windows Vista and all),
the countdown first appearing in photographs and then the cosmic microwave background rather than visible light, and the computer game is plausible given state-of-the-art technology of the era, albeit suspiciously highly detailed.
I was curious to see how the Cultural Revolution would be portrayed...
You've got to change mental gear to "Chinese TV series", which took me the first couple of episodes. Mostly in terms of over-acting and use of music, though the portrayal of westerners is always amusing. It's somewhere between Anime and Korean Action Movie with just a hint of Bollywood.
