By your statements, it would seem that you've all seen more than a few of these kinds of films in order to have really found them all that annoying...and you'll probably keep on watching them for as long as it takes to either give up on the genre completely, or keep holding on to the hope that you'll actually have a satisfying ghost movie experience.
Either way...if you're going to follow the same patterns, then there's no point complaining about it, and if you're gonna quit right now, it's not really worth comment.
Here you go, just what you need...
