It's always been a messy show with unclear direction, but we'll see where it goes. The new setup can be interesting, it was more juts how jarring it was and made last season seem useless. Plus the Lexi stuff just seems plain stupid, but we'll see.
IGN's review was a bit more kind than I think it should be, given the lack of continuity and large amount of cheesiness, chalking it up to a "tonal shift". http://www.ign.com/articles/2014/06/23/falling-skies-ghost-in-the-machine-review
Pretty much all the [mainland] European zones have it, moreflicks is awesome for finding out who has what. Click the Netflix logo under 'Watch it now on:' to see the list.
Hola.org is a free way to access any zone.
LPT: you can use JustWatch to find where a show is available for purchase or covered by a subscription service. Right now, it seems Falling Skies is only available for purchase in the US, but keep an eye out!
Wait... There were actually Falling Skies tie in comics/graphic novels? How have I not known this.
