The creepy Snickers Halloween commercial is back

This ad ran all the time last Halloween, and now it's back this year.  I don't really understand why, but something about the combination of the mask and weird voice is scary.  Like legitimately disturbing.  Does Snickers know this?  Are they doing it on purpose?  Everything about it looks like it's meant to be funny, but it's not.  It's freaky as hell.

Also, I'm not sure exactly why I'm writing about TV commercials so much.  I get the feeling people like it though.  Too bad there's not a job like "TV commercial critic," cause I could kill at that.
