In a nutshell, if you had found the Burari case intriguing, this show will not disappoint you.
The screenplay is a nice adoption of the original story where the key details have been preserved while making changes where there was an opportunity to add the fiction angle and also spin a meaningful story. The narration is good and sets up the premise to make you want to pursue the story despite knowing it from the Netflix documentary. While the facts were known, a story is always better when told in a way where you can perceive the psyche of the characters from their own PoV, even if it was actually the director's cut.
The Netflix documentary was really good and actually compliments this show. Without that initial foundation this show wouldn't really have the impact it is meant to have. However, documentaries are just facts and that was what it was in this case too. So a webseries that actually brings those characters to life and makes them narrate their own story..that's the main reason you don't want to miss this.
Overall a good watch, however, some characters haven't done much justice to their roles. And adding unnecessary characters and giving them screen space was a turn off. Nobody is interested in the personal lives of characters other than the victims here, so adding that extra background story for Tamannah's character was totally a filler and deviates the viewer's attention.
