So essentially they showed off character traits and dynamics we all already knew they had?
I would say this was character rehashing, not development.
I would disagree for 2 reasons:
1. You cannot assume every person watching FTWD has experienced all the character dev in TWD
2. You cannot assume every FTWD character will develop and become someone we have already seen in TWD
If Travis becomes Rick and Madison becomes Carol and Chris becomes Daryl.... etc then we can call it rehashing, but none of the characters are even at the stage where we first met the majority of the cast of TWD.
IMO FTWD is unique because you have a group of people who are on their way to becoming survivors.... TWD handed you a group of survivors and took it from there.
FTWD isn't breaking a ton of new ground I agree.... I would have preferred to of seen a longer more detailed unfolding of the zombie apocalypse.... but I think they blew that chance and jumped to more familiar ground.
However it is a different setting, different types of people, different challenges.... we will see if it gets interesting or if it sputters out.
