I put this into the Netflix queue on a whim. But it's #214 on IMDB's top 250 movies of all time (as I type), and was nominated for Best Foreign Language movie last year. (It's Argentinian, and you should see how it did at the Argentinian Oscars! They thought it was the best movie ever!)
It is actually a collection of six shorter movies, with no particular relation other than having characters dropped into stressful situations. The IMDB lists the genres as "Comedy, Drama, Thriller", but be warned, the comedy is pretty darn dark.
Summaries: (1) passengers on a plane flight realize they seem to have more in common than one might expect; (2) a waitress and a cook at a late-night restaurant deal with an unpleasant customer; (3) a road rage incident on a remote highway escalates dramatically; (4) a demolition engineer reacts poorly to having his car towed by a rip-off company (yeah, they have those in Argentina too, I guess); (5) a father tries to cover up his son's involvment in a fatal hit-and-run; and (6) a bride discovers her new husband's infidelity and turns her wedding into an emotional roller-coaster.
I enjoyed some more than others, but all were watchable. It put me in mind of the old "anthology" TV shows, like Twilight Zone and Alfred Hitchcock Presents. Certainly such a series could thrive in these days of cheapie video?
