This review may contain spoilers. I can handle the truth.
I can't stand narratives like this. They just cram fluff into their pedantic, one character per episode structure. Finally, in episode 6, we get characters we should have had the rest of the show with the Burton family. If we spent 6 episodes thinking Burton did it and then have it revealed that he didn't, that would actually be interesting. Instead we have this drip-feed plot, more interested in keeping up suspense by withholding information and progression for "big reveals", than building any kind of actual tension.
