I found that distracting as well, pretty sloppy with the lighting.
Re The Talking Dead after it, a statement from the producer said that 'man was the biggest threat in this season but won't be in the next'. Make of that what you will. He also said something about major set-pieces being worked on, but it would have been more surprising if he hadn't said that.
For what it's worth, I'm still enjoying it and, although the finale could have been a bit more explosive, I think it came to a decent conclusion.
