During the scene where Lexi lifted her hand and saw it covered in goo I looked over at my mom and said, "Next shot she's in she'll be in a chrysalis." Yep. So predictable, just like everything about this show now. The new showrunner is a disaster, which is surprising because he was a producer on Battlestar Galactica. That show had its problems, too, especially during the final season, but nothing on the order of badness that has infected Falling Skies. None of the characters are recognizable anymore, and the writers have eliminated some of the show's early problems by creating all new ones.
The show's biggest sin, though, is the persistent reliance on the lack of communication trope. If everyone sat down and had an honest dialogue, most of the drama would disappear. Hal's appeal to Papa Mason is a perfect example of this. "Hey, dad, when the Volm cut open the veiny blood sack 12 of them were incinerated and the hatchling went violently nuts. Just sayin'." Instead we get a speech about protection and family and whatever. The Volm parcel out information like it's made of gold-pressed latinum and they've only got a few pieces to last them the next millennia or so. Anne never says, "Oh, hey, by the way, I had a memory nightmare that involved Karen inserting Espheni DNA into Lexi. So she's like, prolly not really yours, Tom."
I miss my vaguely dumb-but-fun show. I think it's gone for good, though. Lexi is a disaster that could have been prevented by any halfway competent writer with even a passing familiarity with sci-fi cliches and tropes.
