Running upstairs when the killer chases them. Where are 你 going to go once 你 reach the last floor? And, as has been mentioned, going alone and unarmed to investigate something clearly dangerous.
If 你 get warned, then 你 follow it. Don't go all "wow theyre stupid" and continue on your merry way! Theyre warning 你 for some reason! Oh and god damn it, if 你 are in a 厨房 and there is a 刀 five feet from you, GRAB IT. I know he's coming after you, but still does it take so long to grab a bunch of knives and run. I mean 你 never know if running will save 你 (which most of the times it doesnt)
When the hero/heroine shoots the killer then stands there crying 或者 shaking about it instead of running away... =_= Don't fall to the ground 下一个 to the killer, run away!! Double tap then run!
The biggest and stupidest mistake ever made is going up the stairs and not out the front door. Whenever I see the character go up the stairs, I scream, "NOOOOOOO!!!!" But I think, "you are soooo dead, stupid!!!!!"
1: Doing it. It just never ends good. I guess its because it distracts them.
2: Screaming and running when they face the killer instead of kicking his ass. I mean seriously what is that??? Don't 你 guys have hands and feet to defend yourselves?
3: Going to roadtrips 或者 camping in deserted places. This is like begging for your death.
4: Trying to save someone else.
5: And yes, going upstairs. Except if you're trying to jump out of the window, it doesn't help.
When they either go into a basement without a weapon 或者 torch to investigate a noise 或者 when they run upstairs cause when ya reach the 最佳, 返回页首 floor where ya gonna go out the window?
Jennifer's Body-girl getting a ride with 随意 strangers. Which leads to becoming a demon and eating people. And dying.
And Soon the Darkness-If 你 knock out the guy trying to rape/kill you, 你 don't leave his unconscious body there, 你 KILL. HIM.
Multiple-OH MY GOD HES CHASING AFTER ME! OH MY GOD I GET INTO MY CAR! OH MY GOD I DROPPED MY KEYS! OH MY GOD THE KEY BROKE! 你 can just see all of the "Oh My Gods" on their face during those scenes.
