The reason the season finale of FEAR THE WALKING DEAD was so successful is that it finally revealed what the show is actually about - The effect of the zombie outbreak on individuals in particular Travis Manawa (Cliff Curtis).
Manawa's journey from pacifist school teacher to shell shocked survivor unafraid of using violence happened quickly but it made sense. His two actions in the finale a.) Beating the soldier they had kidnapped to a pulp after she shoots b.) Killing his ex-wife Liza per her request after she reveals at the conclusion of the episode she had been bitten by a zombie were perfect expressions of what has changed in him.
I enjoyed the storylines of the original WALKING DEAD comic book more than the black and white art which I always thought looked unfinished. However, I find the cast and the pre-zombie narrative of FEAR as it turns into a full fledged epidemic to be potentially more interesting than the TV version of the original WALKING DEAD. Curtis as Manawa, for one, is a vastly superior protagonist than Rick Grimes as played by Andrew Lincoln who IMO just doesn't fit the Rick character. He doesn't seem hardened nor particularly expressive as he encounters all types of horrors and conflict and death.
I really look forward to where this show is going with Manawa's transformation as well as what the sinister Strand is up to. I almost gave up on the show earlier in the season as it seemed nothing was happening but I am glad I didn't as it is now well on the way of realizing its potential.
