I didn't like the second episode quite as much as the premiere pilot episode, but it was only a fraction behind. The storyline was once again great, and the events that took place were interesting as well!
I also enjoy the occasional glimpses into Keira's life in the future in 2077 - they add a lot into her character's development.
A lot of interesting events - won't spoil anything - but I definitely look forward to the next episode! This show is great!
