A Post-Murders film about Lizzie and Emma

The 2014 film "Lizzie Borden Took an Ax" with Christina Ricci addresses your questions at the end. Don't listen to the dullards who say this is a bad movie because of the anachronistic music or whatever. Here's what I say about it in my review:

I just watched this version and 1975's "The Legend of Lizzie Borden" with Elizabeth Montgomery back-to-back and I give this one the edge. It's a little more compelling and has an excellent edgy soundtrack, albeit anachronistic. People complain about the music, but it's not like it's anything new to apply rockin' soundtracks to historical movies; "Marie Antoinette" did it in 2006 and Spag Westerns did it decades prior in the early 70s. Besides, the soundtrack's not all rockin'; it's diverse, creative and thoroughly entertaining. In any case, I recommend seeing both versions to compare the data and understand what was going on behind the scenes at the Borden abode.

While it's impossible to defend Lizzie's gruesome actions, both movies help you see why she felt she had to do what she did (with 99.9% certainty). Her father was rich, a struggling mortician turned businessman and property developer, but he refused to update their house (they still had a pit latrine instead of flush toilets) or move to a more affluent neighborhood. Lizzie just turned 32 while Emma was 9 years older and marriage was less and less likely of a potential escape. The stepmother, Abby, was short & fat and pressuring Andrew to change his will for her benefit. The Borden house itself was curiously structured in that there were no hallways and thus one room linked to another, which hindered privacy. In short, the household was a ticking Victorian time bomb with mounting hostilities waiting to explode.
