I always recommend to watch the longest version of any movie or series.
If you are afraid to watch television series about the war of the Three Kingdoms of China that are more than 30 episodes long then I recommend you to watch the extended version of the Hongkongese movie "Red Cliff" that came out in 2 parts in 2008 and 2009.

The live-action Chinese television series "Secret of the Three Kingdoms" that came out in 2018 lacks action. The longest version of 54 episodes long.
