i really am glad that they scaled back the dialogue. i hope they keep the minimalist, grittier, almost documentary style approach instead of filling episodes with crappy dialogue and annoying "character development". i'm all for character development, but i just thought tWD has done a bad job of it, especially in S2. i thought the scenes in the hallways of the prison were the most intense of the series because it wasn't just a pure zombie slaughter, there was building tension as they turned corners and the sense of the unknown at each turn.
for those that have read the comics, i think most agree that the material that will be covered in S3 (and maybe S4? not sure where the season will end) is the strongest.
