To start off with the good, I will say that the show "sounds" very appealing (deadly virus outbreak on a massive secluded base in the arctic). The general setting/premise is solid.

The show fails however in many facets. The acting ranges from mediocre to sub-standard, though I don't blame the actors. While I can't say I enjoyed any of the performances, The writing is where the show falls apart.

If you tasked someone to find a team of writers to do a project, but instead of doing any work finding the right writers, they just hired a football team (no offence to football teams here), you would have the quality of writing in this show.

The characters typically do not act rationally (rationally referring to how a person might normally act under the same circumstances). Conflict feels like it is created on the spot, and often leads to very unrealistic sequences of events.

The show has poor dialog, and very undefined characters (their personalities seem to change radically without a proper basis as to why).

I could go on, but I would like to end on a positive note.

Despite having it's serious flaws, you may find yourself still willing to endure this series. It has mystery, it has action, it has zombie-ish themes, and from time-to-time has a few moments.
