Lately, I've been thinking about whether the recent spate of home-invasion movies ("Funny Games" remake, "The Strangers) is a commentary on:

1) the insecurity we feel in our homes due to post-9/11 lies and wiretapping from the most powerful sources in our nation, or
2) the insanity of going to a summer home/vacation spot when oil is at $130/barrel, or
3) nihilistic youth disgusted that the "greatest generation" led to a generation of greedy-greedy-mine-mine-mine baby-boomers.

Or maybe it's something else entirely. Suggestions in comments.
