Is this show worth starting from scratch and binging?

I was watching FTWD, and was really getting into it, until I kept noticing complaints and dissatisfaction about the 'reboot' with S3 or S4, whichever it was, and it just generally being dumb and turning to absolute garbage.

I watched TWD as it was initially airing, I think I stopped somewhere in Season 3, as the people I was living with and watching it with just thought it was too slow and boring, and I did some introspection and found I was forced to agree. I tried again, and lost interest shortly after when >!Glenn was killed, interest was already declining by the time they were dealing with the huge horde in the quarry.!<

Is it worth giving it another shot from the beginning? Are these just a few slumps in the pacing? Or is there a definitive decline in the quality of the show, as there apparently was with FTWD? Do I just need to grit my teeth through a few bad arcs?

I'm looking for a new show to start watching, and don't really want to go through all of Longmire again, as good as it is.
