I can see why some people would love this. They took all the story, all the characters, all the depth, and crammed it all into all of five minutes, and then upped the action and violence to 11.
The end result was the remake of a horror movie that had some head to it into a horror movie that you don't really need to pay attention to to follow.
In other words, they made it a mindless, soulless, action packed gory mess... unfortunately action and gore without a plot or characters is pretty boring to watch.
