Whilst watching
Trick r' Treat again last night the same thing hit me as it always does.
When Dylan Baker attempts to bury the boys body and keeps being distracted by Brian Cox, the boy is clearly alive and trying to cry out. Once he's killed him and finished with the grave he goes into the house empty handed meets his son and they go into the basement and begin carving the kids head.
This sequence is just wrong. At what stage did he lop the kids head off? It wasn't when he was in the grave as we see him begin to fill up the hole with soil.
In the context of the film which beautifully slots together each strand it stands out a mile that this is one major error.
