I enjoyed the trailer.  My mom doesn't like things like Dead Space 2, but she doesn't disapprove.  I played the demo right in front of her and all she said was "Ugh...that's gross.  That's terrible.  This is creepy.  Eww."
I love the first one.  But it wasn't scary to me (desensitized)
Doom 3 ruined horror for me because that game scared the hell out of me.  To me, Dead Space was just an amazingly spectacularly fabulously awesome third person shooter with mega-gore thrown on top for some extra flavor. It also had a bomb-ass story.
I'm gonna love this one too.
