Thirded.
I'm not a fan of the original but I like Naomi Watts and her quest to cry and suffer through miles of celluloid. I think the point might be simple, but it is important point to make, as Devildoubt said, "what an actual home invasion/murder would look and feel like," and it isn't fun.
Someone mentioned seeing the trailer for this in front of NCFOM, and if the original is interesting in any way to me, it's because it makes me think I should feel guilty for enjoying NCFOM so much. Compare this scene to similar scenes of Chigurh in No Country [SPOILER]:

You repeat and imitate the dialogue in No Country, study it for meanings and characterization. But here, what's going on is vile. I don't want to see the (implied) violence again, or the suffering, even for the black humor.
Even if the remake doesn't work, that poster is beautiful, a paperback novel version of Watts. Crying and sexualized. The Village Voice review claimed the only real change in the U.S. version was that her character was in her underwear more often.
