I watched the first two but I haven't caught up yet. I thought it was amusing how they did a Fear the WD marathon two weeks into the show when they weren't showing a new episode.
It's interesting to watch how it spreads. I would think that once it starts that anyone with a gun would be shooting a walker on sight which would stop the spread, but I heard that's how this show is different than WD. In Fear the WD people still have their humanity and have a hard time doing that to someone since they still appear to be human whereas in WD, that has gone out the window.
On a unrelated side note, when I try to abbreviate it, why does it change F T W D to FTWD?
