Got worse as it went on

Rating: 3/10 (9 May 2015)

This movie reminded me a lot of Insidious: it started off with a lot of promise, relying on atmosphere and suggestion rather than cheap jump scares or gore. Then, as in Insidious, about 2/3 of the way through it kind of lost its punch and when it came time for the "boss battle," it had become downright silly.
Slight spoiler ahead: I don't understand the claim that this was a particularly original film. The idea that a character in a book can be "real" (here, "haunting" you in real life) is as old as narrative itself. I will say that it was kind of neat how the "haunting" shifted from the boy onto the mother. But overall I found the collection of horror-suspense tropes to be rather cliché, borrowing from Insidious, Amityville Horror, even The Shining, and many other classics of the genre.
I also found the resolution to be rather arbitrary and unexplained. What, she finally stood up to the Babadook and that was that?
