Memorable because, against all odds, there was real change and optimism in that last scene. Tom giving a speech, maybe prelude to his becoming President, Weaver cleaned up, and everyone looking a little older and very good. And Tom's last words, that we learned that we're not alone, were just right for the conclusion of this difficult series.
Difficult because, well, how many times, how many ways, can you tell the story of we humans somehow surviving against overwhelming, all but impossible odds? And our success, based on the premise that if you can destroy the queen, you can wipe out the whole civilization, is not only cliche but was introduced out of the blue just a few episodes ago.
Still, Noah Wylie's acting, and his character Tom Mason and his three boys, and throw in Will Patton's Weaver, especially in this and the previous season, have made an indelible contribution to the science fictional genre of invasions from outer space. It comes down from Wells' War of the Worlds, through Heinlein's The Puppet Masters and Clarke's Childhood's End and Damon Knight's "To Serve Man," which was also a great Twilight Zone episode - all of which were much better stories than Falling Skies. But Falling Skies, because of somehow the realness, the uniqueness, of the Mason family, or the impact of this overwhelming invasion on this family, and its stubborn carrying of hope when everything was against them, deserves to be counted among those incredible narratives.
Perhaps we'll discover alien beings out there in the universe tomorrow - or, if our luck turns really bad, be attacked by them. But till then, Falling Skies will be a fiction worth watching and recalling, with all of its flaws.
