So I'm only on the first season and watched four episodes. I do like how nice and non-provoking they are. I get annoyed with rude confrontational investigators. These aren't criticisms persay, but for 72 hours you could get so much more evidence. 1) sleep during the day/ up at night 2) you need at least 4 stationary cameras with microphones strategically placed besides aimed at your cot. Lastly, sometimes I still cannot make out your recorded evidence even if after it's been enhanced. Having said that, I still really like the show and will watch it all.
