SuperFreak the twist was so fucking obvious in that movie. It was a huge disappointment because I figured it all out way before it told you. Bored me to death. However, if you're dumb enough to be shocked at the twist, then it would be a decent watch.
superfreak the twist is that the other kid died on the fire and the brother is imagining him, blaming the mom for the incident
Hence why the dead kid never really Interacts with the mom
