wow what did any of that have to do with this movie?

Any way the main theme seemed to be about love or making connections, which also feeds the strange behavior of the creatures as its there mating season coupled with the constant attacks of the US, both explosive and poison gas weapons.
I had the feeling that the border post had been recently abandoned and due to the poison gas weapons could still be a hot zone. The condition of the dead creature would also make the attack fairly recent.
spoiler alert
the attack that happens once they are picked up at the gas station i think kills one of them as well.
While this movie has a very similar feel to D9 it was being made before D9 was in theaters so i guess its a case of great minds think alike.
There's a great creative screenwriting podcast with the two actors who go in-depth how this was put together and done. The editing is singled out as more then just an assembly, the story really was made in that last step. Also they talk about earlier drafts of the concept. One of the early version was a fake documentary idea. It also interesting where they explain why Mr Edwards choose and executed this story, a great example of some one looking at what they had and making a story to fit that box, rather then the other way around.
Quite interesting talk.
If you can handle watching some crap sci fi like "Transformers" this more then deserves the look see. Even with its various problems a far better film [images and story working together as opposed to stuff happens with explosions] then the slick crap of Steven Summers or M Bay.
I for one would buy a ticket to Mr Edwards next movie sight unseen.
If any one has film making aspiration this movie is a must see as its the finest example of the dv rebel spirit or low budget sci fi genre in a long time. There have been several horror but not a lot in sci fi so this was a great entry and a serious gauntlet thrown down for indie sci fi.
As a movie with out weighting in cost etc its still a interesting genre piece and stylish post modern creature feature.

This film is available right now on Netflix streaming. In case anyone is interested.

I liked this movie more than I thought I would. I found it to be uncomfortably slow, tho.
