The first three seasons, while not GOT level seasons, were still amazing and filled with dread and realism unlike anything else before. The characters, while awkward at first, have their own arcs that define them as they were and as they are in a zombie apocalypse. Season 1 was a good starting point with the fall of society and the emergence of horrors at every corner. Season 2 started off at sea with some decent exposition but not much in the way of dread, until the second half in Mexico where the most serious issues begin to break the family apart and pit them against odds that prove to be fatal. Season 3 is FTWD's best and most memorable season. It was dark, filled with dread, amazing character development especially for Madison Clark, emotional traumas, challenges both from zombies and humans, and a finale that really went off with a bang. Season 4 started okay but turned out to be a disrespect and disservice to what came before, killing off two main leads (even if one was made by an actor) and essentially acting as if the first three seasons did not matter. FTWD WAS a good show until a reboot in season 4 happened just to connect with the main show.
