Oh where to start?
White tennis shoes. If your some dead creature or killer roaming the woods why are you wearing TENNIS SHOES THAT LOOK LIKE THEY CAME RIGHT OUT OF THE BOX!!!!!!!!!!!!!!!!!!!!!
The words BOO Um get out does not bother me if it fits in but if your character wants to kill them and make them into sausage or something why are you telling them to get out?
Drunks for the love of pete if you can barely walk how do you think your going to get through a haunted trail.
Bottle necks that incapacitate flow and create super groups. When your not a character set for startle you almost feel like you need to be doing a song and dance by the end of that group.
Black robes FOR EVERYONE!!!!! why why why? put some variety in.
FAKE BLOOD IS NOT A MAKEUP JOB!!!! nothing annoys me more than someone with just fake blood with nothing else. no wounds, no dirt, nothing but fake blood. I get annoyed by trick or treaters like that too I refuse to give them candy unless they entertain me.
Random use of Horror movie characters, I mean if you have to use these characters please put them in a set or surrounding that makes sense not just randomly appearing.
Actors who do not even try. Look I understand sometimes you get caught out of spot but when your all set and you come out with the same energy as the cartoon droopy the dog, you're not going to scare anyone unless you're their post man.
And Finally my #1 pet peeve haunts that never change anything. If you do not try or strive to be better then why should I waste my time and money coming back.
