I don't know if Handmaid's tale can be considered Dystopian because, frankly, it is not that scary for two mains reason: Firstly, it is completely unrealistic. No one would separate a child from their parent in any world. Secondly, the characters are unsympathetic. Sure something terrible happens to them but then you realize that they broke the law . Clearly, they are at fault for breaking the law.
This was regularly done in the USSR for idealogical reasons.
> but then you realize that they broke the law.
I'm not familiar with the show, but the law isn't the ultimate arbiter of what you should do all the time. I think this should be obvious from history.
