This movie was horrible

I think it's a beautifully crafted exploration of the nature of grief, and how trauma, if left unchecked, can destroy ourselves and the people we love. I think it's amazing how the movie had us sympathize with a single mother early on, only to flip the narrative and reveal her to be an abusive parent who resents her child, in part because of the related loss of her husband. We realize that this is what the child has been dealing with this whole time. And finally in the climax, she comes to terms with it. And in the epilogue we see her doing her best to manage her grief while being a better mother for her child.

It's a shame that OP and others I supposed just kinda dismissed this as a generic "woman terrorized in house by supernatural" story. But I guess a lot of people missed the point. I remember someone at work asking me like, the ending was so weird, why is she feeding the monster in the basement now? I'm like uh...it's not literally a supernatural monster.
