I don't call this a TV review because it's not comprehensive to be one. I've seen all of the Falling Skies episodes, and I'm prepared to comment plot-wise, but what I really want to comment on is the acting and I don't remember the first season well enough to do that.
In any case, the show is TNT mini-series about an alien invasion that has already taken place by episode 1. 90% of humanity is destroyed by alien WMD. The great cities lie in waste and mankind wages a desperate battle by irregular forces for survival. The big stars are ER's Noah Wyle and Terminator 3's Moon Bloodgood. As a sci-fi fan I am of course interested by the plot, however I have to say that the action is really not great. I'd rate it as mediocre. I think the plot is more interesting than either the action or the acting.
I think the acting is the shows Achille's Heel. Wyle is OK, but he'll never be as good as we was as Doctor Carterin ER. He just has little charisma as the historian father resistance father. It's not his wheel house. Bloodgood is better as the cute the resistance fighter in Terminator 3 than she is as the doctor. She seems markedly less hot for some reason. I wonder if she's gained weight or something.
The acting between the eldest son and his new girlfriend is bad. Either that or its the shitty dialogue. It just seems so predictable and I just don't feel the chemistry.
The middle son reminds me of adolescent Anakin Skywalker from Episode Two, which is of course an unfavorable comparison. He's not a very interesting actor either.
There's a lot of slow moments which relies on the plot between the actors to fill in. This has been somewhat disappointing and not even close to the drama in another TMT humanity-catastrophe series The Walking Dead. It's amazing how the acting/drama is just so much better in that series. Maybe because their lives are always under threat and there's more substance. The slow moments in Falling Skies just seem so bad. The most recent episode - the last 15 minutes was just downright sappy.
The show may need to become dark just to have more entertaining drama. We need some bad guys in the midst of the resistance, just to make shit interesting. The actors maybe just need more content to work with.
Oh and here's one of my big reasons for starting this thread. Jessy Schram is just drop dead gorgeous.
