Ha, it worked well for me, especially with how powerful Ye Zun is even when incorporeal and the chillingly casual way he eats people. It must be an "in the eye of the beholder" thing. :-)

Oh, no, I definitely don't mean that Ye Zun himself doesn't seem dangerous! As I said in my reply to trobadora, what I meant is more that I think Ye Zun's actions are meant to be regarded as (a prelude to) full-scale war on all of Haixing, and I feel like there are ways the show could have conveyed that level of power and danger more convincingly, e.g. by having the SID be more organized and proactive and better equipped, but all their efforts still failing.

There's the scene that Da Qing overhears at the pillar

Oh, yes, I forgot about that! Scenes like that, exactly. :)
