Okay.
After I watched this movie about 10 minutes I felt like I already have seen this movie. But I wasn't right.
The US produced the same movie in 2012. And the plot is the same, sometimes the camera positions are the same... it is pretty crazy.
Said that, I suggest you better watch this "version" http://www.youtube.com/watch?v=nGoe7BdGdlg instead of this one.
Because the only reason why you wanna watch this movie is, that you gonna have some nice action scenes in it - and Red Dawn (2012) is much better as this one.
