It’s hard to imagine a world where slasher film tropes never existed. But back in 1978, as John Carpenter’sHalloween” was arriving in theaters, film fans had no clue what they were getting themselves into.

So, that’s what makes watching this video about “Halloween” such a treat.

The anticipation and suspense they’re feeling as Michael slowly walks towards Laurie is palpable, even just in the audio. And finally, the ending, which reveals that Dr. Loomis thinks he killed Michael, but there’s no body when he looks down, is met with a sort of “WTF” reaction that is rarely found in horror film screenings today.
