I think it's worth a watch, if only for the female lead; she is bloody great.
I agree about the bloke though, and having watched the real "stalker" give her interview I think she has a case for her side of the story to be told. I do believe she has some kind of personality issue, and I also think she is unable (to the nth degree) to interpret social interactions but he and Netflix have allowed her identity to be easily deduced.
She is obviously damaged in some way, and it all feels a bit uncomfortable now
