Sort of like a train wreck, I had to watch this and part seven. Very goofy, but had some interesting yet predictable plot lines.
The whole message of this series (at least the two parts I watched) seemed to be that we humans are bad, bad creatures. According to what I gleaned from these two parts: We and we alone caused global warming, should recycle more, should stop driving and should stop using so much energy. And of course, all energy companies are evil.
A very preachy series! Oy!
Some of the plots were predicable. Like Chandra West and Thomas Gibson in their obvious extra-marital affair, crisis with family, resolve issues during weather disaster.
Randy Quaid was a hoot as he more or less did a reprise of his "Independence Day" role as a whacked-out misfit.
A lot of the special effects were repeated in both 6 & 7 (like a skyline view of Chicago then a skyline of Washington, D.C., with the same carnage in the foreground - or a repeat shot of a power plant, one in Chicago, one in D.C.).
I had to suspend disbelief as the time-line of many of these events and scenes defied logic.
Overall – poorly written storyline with average acting and quirky special effects.
