Haven't watched a minute of the show, but I know there are always 3 sides to the truth. I have, though, read a few articles about the case and the show, since it's been in the news. From what I understand, the producers of the show left out A LOT of evidence that was presented in the case, evidence that pretty much locked up the conviction in the eyes of the jury.
Again, haven't seen it, but from everything I've read, the show has a very clear agenda.
