What Episode Did You Realize That This Show Was Something Special?

I Imagine a lot of people are going to have this answer, but mine was Episode 4, "Beach Reads". It's not an easy task to mix comedy & horror but this episode does it so beautifully. Up to this point I was engaged and interested, but it took this episode for me to be like, "Okay, this show is something special".

I'm interested in hearing if anyone had a similar epiphany about the show but perhaps during a different episode. Or maybe you felt that way since Episode 1?
