Starts out as a great crime drama, then two thirds into the first season switches to some fairly silly horror plot, and then the only character you care about at all (because everyone else is an asshole) gets killed. The script starts dwindling and slowly falls apart. I dozed off during season one finale and didn't care to watch it again.

An effective murder mystery with a strong, well-planned resolution. Unfortunately, it's hard to give any details about the show's most unique (and controversial) features without spoiling crucial plot elements.

Struggled to watch 5 episodes, it doesn't look it's worth the hassle. Looks like a worse copy of "Trapped", cliches everywhere, characters that are completely one-dimensional.

Came for Eccleston, stayed for Tucci, and subsequently stayed because I have a TV addiction akin to Stockholm Syndrome. A good 80% of the characters are so irritating that they overshadow the ongoing mystery of the season. There are a few genuinely good moments frozen in an icy lake of bad ones. While the 4-episode 3rd series tries to wrap up the major plot points, it is ultimately unsatisfying bordering on silly.

Until the 2nd season. No that much sci-fi.

Starts out creepy, stays creepy all the way through. Good tv.
