While I liked their spin on the zombie virus and how the look at the infected as potentially curable patients. There was way too many dumb decisions, boring moments, useless scenes to drive home that a despicable character is in fact despicable(The under the table seduction scene, been there seen that enough in any given American show).
And to add insult to injury, most of the characters besides the protagonists aren't even remotely likable, so I found myself watching a bunch of unlikable characters stuck in a building and wishing they would all just die.
With that said, I've yet to watch the second half, maybe there is a twist that's going to redeem the rest.

Edit after finishing:
The second half is a thousand times better than the first, I found myself actually enjoying the story and laughing in some scenes of the last 2 episodes. Loved the ending and how it was actually treated as a virus, and they bothered actually giving a reason for the outbreak instead of being like "who cares? Just focus on the flesh eating zombies and how our heros survive!" Like most do.
I give it a higher score than I originally did, I would even recommend it.
Bonus point, the romance was well written, not overwhelming just the right amount giving the genre.
