It actually is very similar to another enjoyable parody Royal Treasure with Luo Show, Huang Bo, Sun Hong Lei, Zhang Xi Ying, Huang Lei, Wang Xun, and Zhao Zanilla. I've never seen Running Man, but I imagine it's a lot like it but in a historical setting. The element of parody is intense. You have to treat it like a comedy, and then be surprised by the more touching moments. Royal Treasure's end is more heartfelt though.
