At first I loved the looks of it, but after about an hour....

Questions I have shortly after viewing this:
1. Did she kill the cabin guy intentionally or on accident? If intentionally, why? Cause she's a cold-blooded killer?
2. Again if intentional, why leave her DNA there?
3. Did the movie really have to show me a tampon?
4. The cop later meets her at the bar and says "the DNA matched yours, I have to arrest you". If so, why didn't he go and arrest her? Instead he waited for her at the bar. Also, there was a girl that looked exactly like the main actress, but she was apparently "against witches".
5. Where did the cop keep that weird statue while he was sitting there? He seemed to just pull it out of his lap.
6. Why did she stab the cop? Don't think she'll get away with that. Previously she was only charged with illegal burrying. Was adding murder smart?

Also, where was the plot? Like, that other girl who was rather ordinary and married, I thought they would get into some lesbian sex scenes later. There was clearly tension at the beginning. Nothing happened.

There were more things wrong but these are the main issues that correlate to the plot I guess.
