EVIL! EVIIIIIIL!!!!!!

Let me give you a perspective of things:

I not exactly someone who has a weak stomach. I've seen a good amount of gory pictures, without much trouble. Sometimes, I will willingly search for them. I've also seen a lot of weird and sick things in TV shows, which I was able to handle (for example, I wasn't that grossed out by the toenail scene in the Spongebob episode "House Fancy" and could even handle "Face Freeze").

While watching the review for "Ren Seeks Help", I had to pause it from time to time, because some of the contents being shown was so horrifying.

So yeah, you should be scared.
