The Motive is an annoying piece in that you really don't find much out.
There are a lot of repetative shots, especially of the murder scene.
The young 14 years old son, who committed the crimes ends up being charged with manslaughter and inheriting his families money. I find that fact truly terrible.
W don't find out if he really did slaughter his familiy. A fact that seems apparent. He served 6 years in gaol and then he is released to reap the benefits of his horrific act.
I thought, psychopath as I watched it, no empathy, tears nothing and he wanted the $. The "legal eagles" let him get away with it. Very 3rd world I thought.
