Confronting a Serial Killer

I'm trying desperately to make it through the series, but 4 episodes in and we've barely touched on the subject of Samuel Little or his victims. Every new detail brought up is derailed with a story about Jillian Lauren, and then when it veers back on topic, it just repeats what it had already stated before moving onto something new. It literally never delves into the case beyond a simple mention of the victims and a vague few words from the killer that we're never even sure accurately reflect the crimes, all of it followed up with more about Jillian.
