Review of Cobweb

I really enjoyed the movie right up to the final act, when it became something completely different from what it was set up to be.

Everything that happened in the final fifteen minutes bordered from laughable to moronic, and none of it made any sense.

Why would bullies expect the boy to be home alone? What was their plan? If parents were home, wouldn't they just call the police?

How come the monster was easily able to tear everyone else limb from limb but could just barely scratch the teacher and was easily overpowered by the child?

And what's with that ending? Does it imply that the boy and the teacher aren't going to tell anyone? And the boy is going to live at the house alone? What? Are they also going to hide all those bodies? Why would they? Wouldn't they just call the police?

I heard these inconsistencies being explained by the movie being from a child's perspective, but I find it really hard to suspend my disbelief when the rest of it is so grounded in reality.

To me, it just comes off as them not knowing how to finish the movie in a way that would make at least a tiny bit of sense.
