I totally understand, that if you have seen the Original movie from the 80s, you won't feel comfortable with this. Or it is very likely that you don't feel this movie at all. You are missing the grittiness, the dirtiness of the original. This actually is a more modern and more smooth looking approach and retelling of the source material.

That being said, it does not mean it shies away from some very irritating and disturbing things that happen to the characters here. And because this is a show, that spans 8 episodes, it is able to dive further into those characters. Which gives them more motivation and gives them more background. It works in the shows favor.

The actors really do their best and this new take will either enlighten you (better to try something different than just copy something 1 to 1, yes?) or annoy you. Be open minded if you can and you get more in depth - since I have not read the source material, I can't say how much is still probably missing from it. But it does look like we get a lot more than the original film was able to convey - just due to running time issues alone
