Hate gore stick with PG-13!!!!
Too many complainers about gore for the horror genre. Those without gore are just to lame and tame and boring to watch. They are not scary and if you think they are, then you must have some issues to take care of. Get out of that closet from where your hiding and enjoy the real great stuff. I think these people that complain about gore are the PG-13 horror lovers.
I am a gore watching freak!!!
If it don't have it, it isn't worth the watch.
