What waste of time! The last episode (8) gives you a hope that it will get better, but if there is a perfect single word to describe this season finale of Falling Skies is disappointment.
I can't imagine what Steven Spilberg had in mind when he supported this completely boring series, all it's a mess, weak characters, a few and slow action moments, almost nothing of Sci-Fi plus a horrible background history, show that unfortunately that series doesn't deserve a second season.
And this episode it's a combination of all this factors, and more an unwillingness to hold a sloth and a final decent, pleasant to the public and fans of the series.
One thing a can say to you: if you came through all the season to this episode it's better you expect nothing good and maybe you can feel comfortable watching to this.
