Some viewers dont like the writing, other viewers dont like the fact that its about a female version of Rust and are using the fact that others don't like the writing to shit all over it. They will complain about "pointless" scenes and point to the flashback where Navarro meets the midwife who is busy delivering a baby. Or they will complain its "trying til had to be political" because its touching on real world issues (as opposed to the other seasons apparently). Others just don't like the writing - The dialogue is kinda stilted.

Others are caught up in the mood of hating on New Thing and are now looking for flaws everywhere. These people are dense as fuck and will point out things as plotholes, despite those things being explained.
