Never really gripped me either - they seem to have a fascination with the weirdness that ensues when groups band together to survive, and I got that early on - the stuff with The Governor for example, and how his personality influenced the attitude of his group, was interesting and really well executed. The survivors at Alexandria however, were drippy and uninspiring, and that seemed to permeate the entire season - by the end, I wanted the walkers to get in and liven things up a bit.
I'm still with it - but this season was a low point.
