I had said at one point that I would be very disappointed if Andy, as the guest of this trip, would turn out to be the killer because it was a boring, overused trope. For awhile, I was afraid that the show was absolutely heading in that direction.

Then it turned.

The show was very intense and powerful. I really enjoyed the mystery and I found Darby to be an outstanding protagonist. The other characters all were well done. There were a few of the other characters who were just there and were not involved in the main story that was being told, but that was alright.

Admittedly, the show did turn to another old trope a its solution. The renegade AI. 

The AI known as Ray was shown to be the reason why Bill was murdered, but it was a bit of a change. Ray did not go off on his own as all AIs are destined to do. Instead, he was following what he thought was an instruction from Andy during a rant over his anger. Andy was anything but innocent here. His temper and his violent streak certainly led to the beginning of the deaths that was going on.

However, the trick of making the little boy Zoomer the person who injected Bill with the killing dose of morpheme, because Zoomer was playing a game designed by Ray. A game of doctor, much like he did in the first episode. That was a clever twist that I did not see coming. I did think about Ray early on in the episodes, but I did not go any further.

This was an excellent limited series with a protagonist, played by Emma Corrin, that is awesome and fun to watch. I love smart when it comes to characters. And Darby was very smart.
