I really liked the acting of Lenny and John Lynch. No way did it need to be 90 minutes, but I do like how they delved into the backstory.
This season is mostly about trying to save people that cannot be saved. If you go out of your way to save people it might (and in most cases in this show) does get you killed.
Eastman tries to save Morgan. Gets him killed.
Glenn tries to save Nicholas. Gets him killed. (probably)
Morgan lets all those Wolves run away. Could have gotten Rick killed.
This is the central theme of this season.
I didn't like how we the viewer were supposed to believe that Morgan was cured and became some Matrix type walk the earth type character in a few short days.
I really enjoyed the Eastman character. He had a compelling story, wish they didn't kill him off.
