I haven't looked too much into the case besides the show, but I'm sure it's biased in its own right.
Honestly I came out of the documentary with the feeling that Avery was definitely guilty, but i also got the feeling that the police tampered with some evidence to give themselves an easier time of things.
Dassey is the one I'm less sure about. He probably knew something about whatever happened, but I don't think he was as intricately involved as they made him seem to be. That poor kid could have been duped into going along with whatever story they wanted to prove.
So here is what I take away from this show 5 episodes in:
1. The Hills Have Eyes was obviously based on people from Wisconsin. Everyone literally seems to be borderline mentally retarded.
2. The big defense is the Avery family is a bunch of borderline mentally retarded country folk who are too stupid to do what they are accused of doing.
3. In the same breath that the defense says the Averys are too damn dumb to do these crimes they say the person who left the car at the junkyard was an idiot. The lawyer then goes on to say they had a car crusher and alludes to Avery being smart enough to know he should have crushed the car.. So what is it? Is Steve too stupid to have done these crimes but too smart to have left the evidence like an idiot?
4. The almost retarded nephew was coerced by the cops.
5. The Wisconsin accent is atrocious
6. Yeah. Yeah? Yeah. Yeah! Yeah? Yeah. Yeah..they say yeah a lot..
7. They really like NASCAR jackets
