I am not here to say that everyone criticizing this series is wrong, but that everyone should form their opinion on this drama by watching it and not by reading reviews, either positive or negative.
Personally just today I've said 'this drama is not for everyone' to a friend of mine that asked me if she should watch it or skip it when i told her i had binged watched it. I did say that exactly because this drama is NOT entertainment, it's not easy and it will make you feel uneasy. It's frustrating, it has a desperate edge and heavy meaning with almost no hope, characters are not lovable and many moments will definitely make you cringe while watching.
So no, it's not for everyone or not for every moment, or for every kind of mood you are in. I would totally say to not watch it to someone who doesn't like heavy depressing content, i would say not to watch this to anyone looking for some relax and light content, and so on and on.
If someone who is looking for entertainment watch this and is disappointed based on the development of the plotline hence gives a low rating because of that it's not an objective or fair judgement. I don't like splatter at all, most of the time i find it gross and cheep but if i watch a story whose plot requires lots of splatter and i don't like it i don't immediately assume that's the drama's fault, but that maybe my personal dislike makes me a less objective judge on the value of the product in general and of the value and enjoyment it helds for the audience it's been specifically created for. So everyone has the right to leave any comment or review or rating, and everyone is entiteld to their own opinion on this. Personally though, when i read some reviews before deciding if i wanted to give it a try or not, I imagined this drama to be completely different and very poorly done. I almost gave it up without trying it amd i would have if Netflix did not have the autoplay for new series.
The first minute of hellbound starte automatically for me and it made me curious again so i left it running, still thinking i would be bored or find this ridiculous. Instead the more i watched the more i was disturbed by the deeper thems this drama presents. It's not the 'angels or demons' thing that's interesting, those are mere plot devices to present the truly scary monsters of this story: HUMANS. The supernatural creatures that appears from the start have no other role than being literally the deus ex machina to explain the story.
What dragged me into this drama unwillingly and by the hair, is its bleak commentary on our society and culture through a religious metaphor. I have not found enjoyable one single second of the 6 episodes, yet it made me think about aspects of human nature that i generally prefer to not dwell on too much because they are hard and unpleasant.
So if you are looking at ratings and review of Hellboud before starting the drama itself i'd say it's safe to assume that all the votes in this page are not exactly left to comment on the value of cinematography, writing, directing, and acting of this drama, but more of an expression of what this drama has meant to the viewer in terms of meaning of the plot and it's development or the social commentary that reside in the deeper level of the story. Personally i did not enjoy it, actually i quite hated it, yet i watched it all because to me every episode left behind welts of hurt and a hunger of thoughts that dramas i've loved and enjoy deeply rarely have.
