The first was was just a so-so movie, why would I watch a remake?
It would be better IF the kids were in South Korea and US dependents of soldiers stationed in SK that all got killed in a surprise attack by the North. Now that would be interesting.
First, the original was one of the most moving motion pictures I've ever seen. I walked a mile back from the theater to my house, with my grown daughter who had seen it with me. Neither of us could say a word.
Second, in my experience remakes are never as good as the original. I'll probably not bother to see this one, unless I see some really spectacular reviews. The mere fact that the producers would avoid a real adversary, like China, in the interests of making money, tells me all I need to know about them and the movie.
