I liked episode 2 for what it was... the tech side of the episode didn't seem to matter as much as the relationship it destroyed
such a classic parent/child relationship that they just enhanced with sci-fi technology to make you think of this dynamic in a new interesting context
But yeah ep 2 was a little bit slower and slightly less interesting, but still a GREAT black mirror tale IMO
edit: i forgot about the pinnacle moment of the episode too, which was probably my favorite part and I was just like "OF COURSE, *****! DIDN'T YOU SEE THIS COMING!!!!"
