Well, I consider it one of the best and quite realistic series, the romance there is quite bearable - don't be offended, but in almost every historical series from China there is much more of it - I otherwise like historical series and many Chinese ones are very good and I consider this melodrama as a local specialty and I don't mind it at all...
Well, the first two parts. When they go to Mars, it gets a bit boring but still good.
At that time, in the sixties and seventies, I was a big fan of astronautics and I experienced reality. That's probably why I appreciate that line so much -- what if everything had been different and the Russians had been the first on the moon, it was quite realistic, if not for the two-year interrupted development of the N1 rocket and Glushko's reluctance to supply suitable engines because he hated Korolev, but you probably already know that --
I just finished watching the Chinese series about Admiral Zheng He from 2009, it was finally with subtitles... beautiful, although sometimes the tricks are worse than today, but you know that... and melodrama to the max. But I really enjoyed it and was excited ... of course, sometimes the villain may not have been such a villain and vice versa... but that's everywhere, isn't it?
The advantage of China is that the screenwriters don't even have to invent much. China's history is really too rich. Okay, I'm just starting Three Kingdoms from 2010, unfortunately with Iranian subtitles and the translation is not very good. Well, you can get used to it.
