Unoriginal though this sentiment may be; the first thing I'm going to say is 'if you haven't seen Texas Chain Saw; go watch it'. Although that seems a little redundant; if you like horror movies enough to have found yourself on the corner of the interwebs where people watch one every week, then you have almost certainly seen this one a couple of times already!
With that in mind, I'm not going to be especially mindful of spoilers from here on in.
