Other horror films I like lots, for context: Hereditary; It Follows; Halloween; Us; The Host; Ringu (Japanese Ring); Gonjiam: Haunted Asylum; The Haunting of Hill House; Turn of the Screw; Cabin in the Woods
Tl; dr: Really fun viewing, and worth watching all the (short) films. Would be good on Halloween! Definitely watch in order for maximum enjoyment.
Color me shocked. I went into this film series with very low expectations. In fact, I started halfway through the series because someone said that would be fine. Honestly? I was a bit confused and figured I would just start back at the beginning. I'm now convinced you SHOULD watch all the way through; the character grows on you. That matters.
Started out by hardly paying attention and mostly watching my phone, until I realized I was riveted, watching the TV more than my phone. (My teenage son had the same experience when I watched it with him the second time through.)
By number 6, I was hooked to the screen. I even downloaded 4-6 to watch on a flight to Florida - and barely realized I'd flown! I won't provide spoilers but will say that the last one has an amazing ending that I loved. My teenage son agreed - and he's a horror snob (A24 films only!!) - so that's saying a lot.
Definitely watch this. Turner Clay is an amazing human and tells a really good story with the series. Start at film #1, and you'll hopefully be as hooked as I was by the time you get here! Definitely worth the build to the end.
