I was also surprised by this second trailer. The first trailer made the movie look very different.....But I think I might know what's going on. It's still the same premise with more action. I will not elaborate more because if true, it spoils things.
A trailer doesn’t need explosions and 1000 cuts to get the attention. It was enough for me; I got the premise and made me interested. It looks like it’s going to be an emotional story not a horror movie. (people seem to expect the wrong movies from him lately!). ;)
