Just watched it. I actually really liked it - it was a great representation of PPD, and it was left open to interpret if she was really being haunted, or if everything she was experiencing was a manifestation of the PPD. It was full of tension and suspense. I think they could have developed the backstories of the ghosts a bit better, but at the same time, what we did learn was what Sara knew. If there was more backstory, there would be less ambiguity about whether or not what she was seeing was real.
That smarmy psychiatrist really pissed me off, though. He spends half an hour with her, and she very lucidly tells him that she knows she hasn't bonded with her baby but she very much wants to, and his answer is "Nothing you're feeling is real. You need anti-psychotic meds."
My personal takeaway is that the entire experience was hallucinatory, which is why there were no visitations (even from the dirtbag father) after she broke through the PPD and bonded with her son. The tension at the ending was just her fear that she would experience PPD again with the next baby.
