The general story and plot line of this series was decent, but even only 10 episodes seemed long and drawn out. The core problem was excessive melodrama.
Several people's backstory is told in narrative detail (regularly breaking the sense of realism). The acting was quite a bit over the top, which is probably the doing of the director rather than the actors. I did like their choice of actors; with what they were given they did a decent enough job.
Fair advance notice: the ending is an anti-climactic letdown. Sigh. You'd think by now producers would know to start with a sharp script or don't do the series at all.
Throughout this entire series I regularly wondered if anyone in 160 people had any real leadership ability or any knowledge of survival at all. The first thing they should have done was organize into subgroups based on skills and taken care of water and food requirements. Not knowing the wildlife situation, quality weaponry should have been on the agenda; perish forbid a hungry bear would have come through the camp. But it seemed there was little or no organization. Some people tried and accomplished a little through emotional encouragement... but aside from the old guy that left early on, none of them seemed to have a clue how to survive in the wild. (Seriously, they're low on food and what they focus on is a bathtub? They're kidding, right?)
The second camp fared better, but they were located in a much better spot than the first camp. They pretty much had water and food handed to them on a platter. Not much to lead there... but at least they had things in order. Even then, some of the things that went on at the second camp were pretty illogical script-wise (sorry, no spoilers).
Overall there was too much angst, too much emo, too little focus on getting their act together and surviving this thing. There are so many other gaping holes in the logic of this that I can't go into them without spoilers. It's an okay series, but the ending is one of those "Really? They're stopping it there?" type of things. Disappointing is the key word. It's like the writers just suddenly ran out of imagination, time, funding, or all three.
This series is an "okay" watch, and some people may enjoy it. But for me it was only mediocre throughout, and a poor conclusion. They could have done a lot better with this unusual and potentially interesting theme.
