You have no brain, and likely no soul if you think that about this movie. Just because a movie isn't lighting fast paced and has special effects and bang boom every 4 seconds, along with extensive boobs, and blood... Eesh, kids these days. Well go watch your brainless crap you unholy to imbecil.
On the other hand, if you are open to an atmospheric, paced movie, meant to build a sense of actually being there to help intensify the fear, again s.l.o.w.l.y. And to creep you out with a ghost that does what many fear from childhood, things that go bump in the night, and sometimes even during the day. The movie then goes into a cool and fairly unique direction of scaring the viewer and making them care fir the characters, while not baby walking us through the whole back story, as if our brains cannot take cues and hints and suppose what that story might be.
As to why she wkukd go to the cabin, she was tormented by her pain from her oast for certain, but her good memories of the place were there too... And she went to get away... So where do you go to get away... Your old cabin in the woods sounds good to me.
The end brings into the movie that ever so forbidden subject, REAL spiritualalty, and forgiveness, and perhaps even a hint of God.
That is probably why there are so many negative reviews and it has a low rating.
But alas, people mostly seem to want Battleship, instead of the Silence of the Lambs these days.
If ADHD was a country, it won the war on America in the mid 90s to early 2000s...
