Monster: The Lizzie Borden Story combines documented events with substantial fictionalization. Recent Netflix and PEOPLE fact checks make several of those differences especially clear.
1. Bridget and Lizzie's Romance
The series presents an intimate romantic relationship. Reliable historical evidence does not establish that Lizzie and Bridget Sullivan were lovers.
2. Nance O'Neil's Friendship Began After the Trial
Nance O'Neil's documented friendship with Lizzie began after the trial. Netflix's ending explainer notes that Lizzie met O'Neil after the trial in real life.
3. Emma's Conflict With Lizzie
The sisters' eventual estrangement is historical, but PEOPLE's current fact check says Emma defended Lizzie during the trial. The show's more dramatic confrontations are not all supported by evidence.
4. Aileen Wuornos
Lizzie and Wuornos lived in different eras and never knew each other. Their connection is entirely fictional and thematic.
5. Private Conversations
Many intimate conversations in the series cannot be verified because the historical record does not preserve private household dialogue.
6. Motive and Psychology
The show constructs a clear psychological explanation for Lizzie's alleged actions. No court established that explanation as historical fact.
7. Bertha Manchester
Monster links Lizzie to the 1893 killing of Bertha Manchester. Current historical fact-checking shows that this is impossible: Manchester was murdered while Lizzie was already jailed awaiting trial, and Jose Correa de Mello was convicted in the real case.
8. The Post-Trial Story
The series reshapes later events. The real Lizzie lived until 1927 and spent many years at Maplecroft with Emma.
9. Bridget's Historical Role
The real Bridget was a household maid whose testimony mattered to the investigation. The series expands her into a central romantic character.
10. The Finale
The afterlife sequence connecting Lizzie, Maggie and Aileen is symbolic fiction rather than a historical event.
What Remains Documented?
The Library of Congress records the Aug. 4, 1892 murders, Lizzie's Aug. 11 arrest, the June 1893 trial and her June 20 acquittal.
Quick Answer
Is Monster Season 4 a documentary? No. It is scripted historical drama that uses the real case as a framework while inventing or rearranging relationships, scenes and events.

Fact-check note
This article distinguishes the Netflix dramatization from documented history. Lizzie Borden was acquitted in 1893; claims about guilt, private relationships, motives and events not established by surviving records are described as fictionalized or disputed rather than settled fact.
