It's the movie with Liv Tyler and Scott Speedman as the couple who go away to their secluded mountain home and are tormented by three masked uh, strangers. Trailer here. It should hit your shores in August.

I haven't seen it yet but I watched Funny Games this week, which has a somewhat similar plot. Also similar to Ils, which I haven't seen either. I still don't know what I think about it. I too think my horror taste may have been stunted by crap.
