Just saw the trailer.
I just had a peek at the trailer on Youtube, and based on what I saw I can't say I'm too impressed. It looks like a stock good-guys verse bad-aliens kind of flick, when I thought it might be based on the award wining RTS game that came that came out a few years back.
It would be interesting to know what else is in store for this film, but, unless I miss my guess, it's really just a focus group market flick that'll probably earn back its production cost when it hits DVD or direct DL.
Otherwise I'd skip it. There's better sci-fi out there, and this ain't it.
