I'm not really getting any sense of plot development. Maybe it will improve. They're just walking from one place to another, worrying about material stuff.
I saw only first 2 (3 if you count pilot as 2 eps) episoded so far and i agree, this was the main theme and to be fair, i do not like it. It reminds me a bit of Battle LA or those military movies/shows like Band of Brothers...now some guy will tell the group the plan, then there will be half an hour of random action showing how they try to stick to that plan, 95 percent of time its "conquer that hill" or "get to that bunker" or "get into warehouse" etc... the most characteristic aspect of this kind of shows is a all action, but not really a story...
when i compare Falling Skies to The Event, i just finished watching, the Event is sooo much better... it has lot of action too, but all this action does have reason and is backed by some background story, you simply watch it in expectation, the mystery introduced to viewers in the pilot episode will unfold somehow, but there is nothing like that in FS, as they just keep running away from aliens/surviving. The only expectation toward the next episode is only how will they survive another day, but that is not really as intriguing for me as main plots of Event, Flash Forward, Surface, Odyssey 5 or Threshold.
I wonder where is this fascination with almost documentaristic approach to cinematography coming from. It seems to me, they are not really trying to tell a story, they just try to show as "true" as they can the way of living of people in postapocalytic world in some kind of almost "reality show"...it simply has to feel like its happening, but does not really matter what is happening. Form over actual content if you ask me...
Anyway, i still have hope it will improve, do not want to make any final judges based on 2 episodes. Star Trek DS9 was not that great up until 3rd season and its one of my favourite shows.
