Although Letti's story is very touching, yours is more to the point. The excalation of horrors and pseudo-psychological thrill in the movie was such it very soon became ludicrous.
And, Nikolett - no, it doesn't make the shitty movie better. It's all in the mind, soul and heart of the beholder. There's nothing wrong in seeing good things in poor movies, but trying to watch something really good might be a nice change (and killing more than one bird with one stone)
