Here's mine in no particular order:
3.Blair Witch Project
7.The Texas Chainsaw Massacre
10.Last House On The Left
That was hard, only one has any effect now and that's Blair Witch.
Jaws stopped me going in the sea for life and I find it hard to watch Chainsaw due to the amount of screaming. I hate women screaming in films. The worst film on the list is Last House.I will never watch it again,bloody horrible,cruel movie.Not a fan of violence against women slasher type stuff at all,and the older I get the less tolerant I am of it too.
