For those of you interested in the Betty Broderick story, I highly recommend this book:
https://www.amazon.com/Until-Twelfth-Never-Divorce-Broderick/dp/0671726668
I think it's out of print now but I thought it did an excellent job with the case and the people involved.
I intend to watch Dirty John but my God the Meredith Baxter miniseries (or it may have been two movies, I'm not sure) was excellent.
