“He Wei Dao x Guan Yu Wo Zhuan Sheng Bian Cheng Shi Lai Mu Zhe Dang Shi“ is certainly a mouthful of a title, that surely lives up to the lengthy commercial itself, having outlasted its welcome in terms of length.
To be honest, I'm not sure why MAL made me watch this. Sure, it's a nice addition to the Slime franchise, but as a standalone commercial, it falls short. The animation is nothing to write home about and the commercial is far too long for something that is essentially just an advertisement. I've seen far more impressive wooden planks in my backyard.
I suppose seeing Rimuru is nice enough for hardcore fans tho.
