4th season saved the show for me I thought i'll give FTWD a try and boy the first and the second season were so boring.. atleast for me. Third was ok, but the fourth season feels like a reboot. Absolute masterpiece and i'm enjoying dharma and the guy from raising hope. Just fantastic!
If you tried to start with season one and failed to keep on track. Just start with 4, you won't miss too much, it feels like a standalone.
