So, the first episode was less than stellar. 2nd episode was somewhat better. 3rd was booooorrrrriiiiinnnnngggggg. But this last episode was just plain awful! Don't want to spoil it for those who haven't watched it yet, but the writers for this series are either lazy or haven't graduated high school yet (check that: I was writing better than this in high school). None of the characters in this last episode where behaving in a rational manner, and the motivation for their actions and reactions were unfathomable and nonsensical. Plus, from a technical standpoint, their operational and comm discipline was atrocious! From wearing their ship's t-shirts (with the name emblazoned on the backs) to such things as using the ship's name in open, unencrypted voice comms, it was laughable. They've still got a Russian battlecruiser out there somewhat looking for them and they're announcing on a radio the ship's name. They mention at one point they're at EMCOM, and therefore won't answer the radio calls of their shore party, yet they're apparently tracking the shore party's location on a river with the ship's radar. And apparently the radio they take on their boats up the river has exactly the same range as the ship's radar, but shooting a flare gun can be seen from the ship from 30-miles away...in the daytime!
I'm giving it one more episode, but I'm not hopeful. Oh, and as a final idiotic plot device, they take two boats on the shore party; one has the camo-clad equivalent of "red shirts", the other has the three most senior people on the ship (Capt, Exec, and chief of the boat). Naturally at one point one of the boats turns back for the ship, while the other goes off on a hunch into unknown conditions to try to complete their mission. Guess which one continues the mission? I could accept that they changed the world ending disaster from what it was in the book, a nuclear war, to a global epidemic; what I can't stand is lazy writers with patently unbelievable actions by their characters, in contrived situations. <phew!> Rant concluded.
