I used to hate deathcore for a while, but then I grew up and realized that there is some creative deathcore out there, like VOM, or Painted in Exile, or The Contortionist. Great VOM set btw, wouldn't go to this show because I don't like the other 3 bands, but still.
The one thing that really grinds my gears about deathcore is the bad name it gave hardcore dancing. Hardcore dancing at HARDCORE shows is ridiculously awesome. I don't know how or why people started hardcore dancing at deathcore shows, but I think it's pretty lame and really doesn't fit.
