Just rewatched: a few pointless thoughts
How does Brackett not go check on his daughter during the course of the night. I know he was skeptical of Loomis, but just to be safe at least pass by and give her a warning.
Laurie is a terrible babysitter. She is attacked and being chased by a madman so she runs to the house where the kids are sleeping.
Why did Annie park in the garage? wouldn't she just have parked in front of the house or just in the driveway.
