US Trailer reminded me of Skyline and Attack The Block
Not to say it's a rip off or I can explain myself exactly but it reminded me first of Skyline, the way people are reacting to what's going on in the sky and the colors. Then it's like we are seeing large dark Aliens coming from the clouds and attacking people on earth, and it felt like Attack The Block right there.
I sure hope it's better than Skyline, and maybe not as much as a comedy as Attack The Block, but the directing and acting in that movie was excellent, so I would hope it's a sci fi as good as that.
