No, it's not terribly original.
It is certainly reminiscent of Texas Chainsaw Massacre, Halloween, Friday the 13th, etc. in many ways. Oddly, it also called to mind for me a recent movie: Dead Birds (2004), which also started with a bank robbery where people got shot, and the robbers holed up at an abandoned house they knew about, where they get picked off by evil. Unlike Dead Birds, there's nothing supernatural in the movie apart from the killer's ability to take a licking and keep on ticking, but that's nothing new for a slasher.
The first storyline we are introduced to is that someone has been abducting children and killing them. Years later, a woman watches her daughter playing softball.
We also meet a young couple, and they along with the girl's brother and another man are going to rob a bank of about a half of a million dollars. The boyfriend needs the money to pay off loan sharks (I think), otherwise he wouldn't be in it. They're to meet up at an abandoned house where they will split the money and then split up themselves.
The couple and the brother are in one car, the other man is on his own. His car gets a flat, for which he is evidently unprepared, and he carjacks an SUV, which belongs to the mother and her softball-playing daughter, who are forced to come along with him. The three of them make it to the abandoned house first, and violence erupts.
The weakest part of the movie for me were the musical "stings" when the killer shows up or proves to be missing. They were pretty cheesy, to the point of spoof almost.
While the movie isn't very original, I nevertheless felt it was pretty good, and am surprised at some of the hostility towards this movie by other users. That said, if you're going to watch one bank robbers killed by evil in an abandoned house horror movie from 2004, I think Dead Birds is the more interesting one.
