The dialogue has been truncated, which makes it more suspenseful. How? Because the kids get the fear in Laurie's voice. If they were to sit there and argue with her, the scene loses a little bit of its impact. You know that feeling when you've seen an adult lose composure... that's here. We know they're afraid, but I think it's important to demonstrate it.
The close-up of Michael didn't have as much of an impact - meaning, it wasn't full blown, hey, this is what I look like - and I think that was good. Keep it more in the shadows and mysterious.
We also never see Michael fall upon the initial shots. This helps give him that "boogeyman" feel. The boogeyman doesn't fall down, dammit!
Laurie's final dialogue is somewhat indecipherable. I can't tell if she's ASKING "Was that the boogeyman?" or not, but I've always felt like that's what is implied by Dr. Loomis's tone in his reply, as if confirming.
If this is the correct interpretation of it, I like it because Laurie has gone through the movie telling Tommy that the boogeyman is a made up entity, used to scare little kids into behaving on Halloween.
When Dr. Loomis replies affirmative and looks out the window, it's as if Laurie can read his face and infer... yep, we know better than to believe he would be lying down below, dead.
