There is a lot to say about this zombie teenage drama.
The zombie portion is done very well, the only reason I bumped it up to 7 stars instead of 6 is how all of the constituent parts come together to create something greater than the sum of its parts, but this series is not without its flaws.
If you can appreciate good acting, a nice score, great cinematography, and a decent story (and love zombies) then this is for you.
However, if you're a logically minded person then this will be a trial of frustration in which characters will continually make the worst decisions possible.
Whatever you imagine you would do in the character's situation you can almost bet that they will go about things in the worst way imaginable. This is a compounding problem. There is no salvation from idiocy here, only bad decision after bad decision. This can be tolerated to an extent but the frustration only continues to rise.
Despite this glaring problem, everything else balances it out. It's worth watching if only because the dumb decisions benefit from the suspension of disbelief. You will find yourself rooting for the cast and get caught up in their emotional drama. You will find both high points and low points worth celebrating and mourning, all of the braindead decision-making be damned, you'll still be forced to feel something.
It's not the best zombie flick, but it's a damn good addition and a worthy addition to the Z-roster. Don't let this one escape you, just be prepared for the frustration that will inevitably rise.
