Maybe if the movie was released during the #metoo movement, it might have done really well at the box office. It does have Clint Eastwoods daughter in the main role and of course it does have the topic of sexual abuse. There is some reality behind it all which may make some people uncomfortable. 1) because of the subject matter and 2) because of how it handles the topic after it (where it descends into the fantastic and unbelievable).
While I don't agree with everything the movie is portraying, the movie itself says that our main protagonist isn't always on the right side (of her mind) either. So if you try to nitpick, there is a lot you can find here. But if you accept this as a thriller and a bit of social message in between, you should be ok. Sit back, relax and do try to take the positive the movie is trying to tell/sell
