best true story was the entity. not sure with the last exorcism, u see I find it hard to believe u walk up walls or bend back akwardly lol if anything it could be an epilespy fit, my mate fell on floor and moved all weird as if he was possesed lol turns out it was an epilepsy attack he had and it did look scary, maybe this can explain what goes on in exorcisms yea.

I honestly think it depends on the person or whats haunting that person.(im mean possessing person)and the strength of the enity.i never ran into anything of that nature.yet i still havent seen the first movie..send me a copy..lol..

At first i thought paranormal activity was based on a true story, but turns out that they wanted to make it look as real as possable, give u that feel of watching something real. Its a Good movie i think, and would like to see part 2.

The walking up walls, and bending backs, are just hollywood trying to make it more interesting and scary.

I didnt think it was based on a true story..and yes i saw pa!!lol.i also saw haunting in connecuit.i had goosebumps.
