Incredible episode, definitely the best one so far, it was intense and filled with (almost) unexpected events that really makes you wonder how things are gonna develop from now on.
There's one thing that truly annoyed me though, and it's how inconsistent technology is portrayed in this show; one episode you can believe it's technology so far away from us that it looks like magic, but then the next it falls into classic clichés like ships failing after smashing a screen or hacking doors by booping a hard-drive twice with your fingers, complete nonsense straight out of a cheap 80's sci-fi movie.
Anyway, I still don't understand why the book fanboys keep expecting this show to be something different. Just accept it's inspired by the books, but it's not the books, deal with it and move on, the show is very good for what it is and all you keep doing is review-bomb the show with low scores. Seriously, move on.
