I really liked this episode, I thought it showed some new themes and interesting thoughts on how to leave the past behind. When the show stops to be "meta" everything, it's plausible, and the way the show many times feels like a dead end is frustrating but also intriguing. Will they ever find a cure? Is everyone going to die at some point, will there be a happy ending or more importantly: Will it have a message and bring out some very well deserved contemplation. What I like about TWD is that those who doesn't get the show thinks it supposed to be about action but the truth is it never was and never will be about that. What I dislike is, well, it's not about the action but if it's about human emotions I really want to bleed with the characters, feel what they feel, and with Beth being gone a big part of what's human with the show got lost. She was the most real and well written/multi-layered character - It seems like everybody else is quite one-dimensional....(Of course I point out Daryl as the main example....)
I love this show and I don't want to love it just because I've been following it from the start. TWD is a bit uneven, but as most of the characters nowadays, I still have some hope.
