I was surprised to see that there wasn't a dedicated thread about this show, only mentions in other threads.
Frankly I found the first few episodes to be pretty slow and dull at times as the groundwork was laid, but by episode 3 or so it really picked up and became really interesting.
I was so surprised to see one of the producers mention in episode 5 I believe that they liked him or found him likable or something. He creeped me the fuck out from the very start, that super creepy squint/blink he constantly did after almost every sentence was so disturbing. I found the 'behind the scenes' sections with the producers strategizing just as interesting as the coverage itself, if not more so in a way since that's so rarely done, at least integrated within the series like it is.
And what the fuck, Galveston? What a dream jury for a defense team, complete imbeciles that will listen to the defense attorney's bullshit spotlighting on very specific letter-of-the-law definitions and completely dispose of all common sense and context. The same type of morons acquit O.J. Simpson and Casey Anthony, they gullibly get lost in meaningless minutia and ignore reality.
I'm still blown away at how strong the resemblance is between Kathie Durst and her niece, it looks like they could literally have passed as identical twins at the same age.
I have to say though, I found the intro sequence they made to be jarring and distasteful. This is about real people and events and they seem to totally disrespect that, or at the very least be extremely tone deaf towards it, when they decide to commission a catchy song and create some highly stylized intro sequence with it and integrating those real photos throughout. It bothered me more and more with each episode.
