I watched this a couple years back and am revisiting it in light of Gypsy's prison release. The story of DeeDee Blanchard's Münchausen syndrome by proxy is heart breaking- and while this miniseries is somewhat dramatized, it delivers strong performances and convincing locations.
The first five or six episodes are nearly immaculate. Arquette and King effortlessly absorb themselves into the mother and daughter roles. And we can understand how the system failed Gypsy.
Things took a turn when the 1990s flashback scenes and the scenes of Nick's family were introduced- I didn't feel those were pertinent for telling the story.
Overall it's a miniseries worthy of its Emmy award nominations.
