I agree that I dislike their design (at least more so than Wind Wakers and Twilight Princess' design);however, I actually really enjoyed fighting them once I understood how you were supposed to defeat them. So overall I liked the Bokoblins in SS.
I despised the undead ones. When you hit them with the fatal blow they died in slow mo and I was freaked out. Other than that, the Technoblins were annoying because you couldn't just swing like mad like the other ones. I laughed when I saw them though. They're just so dumb!
Why must fans always find the smallest things to nitpick about? Bokoblins are evil; evil is ugly. Thus, it makes sense for them to look ugly. You're saying they look disgusting? Dude, they aren't that bad.
