He was okay but i don't think it needs a running villain theme.
It shouldn't be half another season of Rick vs the Governor, it's gotten tiresome already.
There should be more focus on them surviving different problems not just the villain of the week.
The Governor shouldn't be the M. Bison of the walking dead.
Separate the characters some more, two or three episodes where it's two three or four separated from the main group so it could give a chance to know the characters who they are as individuals & not just part of a main group.
It's like they're better when it's small groups of them.
What about food, ammunition, gasoline.
The cannibals from the book could make for 3 great episodes.
Have different survival problems for different small groups to run into & deal with.
They shouldn't stay in the prison too much longer either, it's becoming stale.
A new location would keep it fresh.
