What has happened in terms of the director etc in s4 and s5?

I watched s1, 2 and 3 when they came out which feels like a lifetime ago thinking about it and noticed recently that s4 was on Amazon. Just finished it and sitting here now it doesn't even feel like I just watched a full season, it just didn't feel the same. Not been up to date with any information on new writers or directors, can someone explain what happened? I didn't mind the season however Its a shame that the main characters of ftwd are kinda getting thrown to the back now and are almost just there as extras
