I'm almost done with season one and should probably wait, but I have been captivated by this program in a way I was also drawn to Diablero which is also on Netflix and very sadly only ran for 2 seasons.
Ever since my baptism by fire when I watched my first Korean film, OldBoy, I've developed this space in my brain where films and series so foreign to the American and British series, films, ideations and tropes, live. A niche where I can go back and puzzle away at them.
If you've seen OldBoy and better still the Vengeance trilogy, it is so far outside the shorthand Americans have for American and European film making because we share much the same culture.
When I'd watch Chinese and Hong Kong action films with my dad, I began to lose interest in American action films with their shakey camera cheats and brief fight sequences when compared with fight scenes choreographed by Jackie Chan or Yuen Wo-Ping.
Horror, Fantasy, Action and all the places they open new opportunities to not only see new content, but we may need to do the work of learning the folklore and stories of cultures so we can fully enjoy the movies and series were more able to watch.
The first Korean Series I watched on Netflix was Bad Guys, which I came to enjoy very much. I'm starting to pick up reoccurring themes in certain character types, the clown, the criminal that's really a good guy at heart, etc.
So HellBound drew me in really fast, and it does take an emotional toll on me, watching this violence and trying to understand what's at play. This is based on a graphic novel or Manga, so it's meant to have a fantasy or supernatural story. And so far no one has fed me all the answers, as American series so often do.
If you come to watch HellBound, come to it knowing that it's not the paint by numbers series or movie making we've gotten used to. It doesn't make sense right away - at least the supernatural elements don't. The people who use the situation to gain money, status and power, that part is familiar.
If you watch the horror film, Audition, if you can get all the way through Audition, you won't have an American film experience you can liken it to. At least not back when it was released. The short film, Dumplings that you can see alone or in an anthology collection of 3 films cake 3 Extremes, which I recommend, was one I found especially creepy, and can't imagine getting an American version made anytime soon.
All of this just to say, you should take the time to watch HellBound, but don't expect to just totally get everything immediately. Store it in your brain, in it's own little box so you can go back and puzzle at it some more.
