I watched it and it wasn't as good or scary as the last 3 ones. A lot of the things also didn't make sense and felt forced. Some questions about the movie:

1. Why did the girl go into Katie's house after she found out she killed her boyfriend. Instinct would tell you to get as far away from there as possible

2. Why did she keep exploring the house when she say her father get dragged, she should have ran out the house.

3. How exactly did Demon Katie get inside the house?

4. I heard somewhere that Robbie killed his mother, is that true?
