Season 3 of Fear surpassed the original show by miles. It still wasn't perfect, but it had a better tone and look, the dialogue was straightforward and easy to connect with (opposed to TWD's weird abstract style that doesn't even sound like people talking) and most of all it had a tense and compelling story.
I'm nervous for season 4 because it sounds like it's going to be more influenced by the original series (truly escapes me why they would want to do that) but I'm optimistic.
FTWD season 3 proved to me the genre isn't dead or oversaturated, just that TWD is. FTWD had some absolutely cringe awful scenes and dialogue deliverance in season 3, but overall I didn't feel insulted as a viewer, I didn't feel like my intelligence was being assumed by the writers. It was a decent enough show that only occasionally left me confused by the characters' actions and decisions. There's a ton of room for improvement, but for the first time in years of TWD and FTWD I actually felt like the positives outweighed the negatives as far as the show season went. Compare that to TWD where I can't even keep up throughout the whole episode because I'm hung up on how a group of people just teleported, how the dialogue is constantly delivered like a 70's comic book, how people just magically acquire grenade launchers or bazookas or some shit, or how cheap the writing feels.
