The biggest problem and the biggest strength of Fear the Walking Dead
OK I am only halfway through season 2, so please, no spoilers.
Biggest problem I see so far: No strong characters like Rick, Daryl, Carol etc. to root for. Maddie is unlikable, Travis is a puss, Nick is a flake, Chris is a psycho, Alicia is a clueless valley girl, Strand is boring and gay, etc. etc. Daniel was pretty cool, but AFAIK he has been roasted alive. I understand Morgan is eventually going to join the show, so maybe he will solve this problem.
This also holds true for the villains. So far we have had some weak army and medical personnel, half-assed pirates, a sinister Mexican abuelita and some narcos. Where is a new Governor or a Negan we can love to hate?
Biggest strength I see so far: No superheroes like Michonne who can kill 20+ Walkers in minutes without breaking a sweat. This totally altered the grim survival mood of the original show when she showed up. The Walkers went from being terrifying to practically a minor inconvenience unless they showed up in a horde of thousands. I really hope they do not change this and maintain the realistic survival horror feel.
