Sian Harkin (Jane)

I’m so confused The first episode was great Second episode was ok started feeling like there were some twists and turns coming Third episode, too drawn out, I don’t understand the point of her questioning or what the outcome of that was? Fourth episode I literally fast forwarded the whole thing apart from when he threw paint at his van. Where was the murder weapon? Why didn’t that girl get arrested for assaulting the boy at the school (what was the reason for that), What happened to the trial? I just feel like they could have made this so much better than it was? Maybe it was rushed I don’t know. They had a good plot but missed a trick here. Feel like I wasted my time watching this. Mother’s acting was not good.
