Yeah I was really nice seeing Kelly again. I've had a crush on her since Trainspotting. And Faye Marsay was amazing. I almost didn't recognize her as the same actress from Game of Thrones, since I found her character there so forgettable. She was magnetic here. I believed she was knew what she was talking about during all technobabble she was spouting at least.
Karen and Blue really made and great and engaging team. I wouldn't mind them being recurring since that seems like it's going to be a possibility now. At least the British girl from the beginning of Playtime is going to be playing the same character in another episode of season 4. And they loaded up a lot of easter eggs that connect the episodes. So getting them to recur is a possibility.
Clever things make people feel stupid and unexpected things make them feel scared

Hey, I thought the same thing. I thought it would make a good mini series.

You just underlined the problem with television, as a whole. The masses crave the pablum, and the industry feeds it to them. I'm guessing the creator of this series knows better. Not everything perceived good, need be expanded continually.

That's the character.

No, the actress who played Karin was horrible, stiff, and wooden IMO.

Not really, no. I'd like the beez to go around killing more people though. Not told to do so, but picking people on their own.
