Javier Rebollo: The Dead Man and Being Happy (2012)

This Spanish-Argeintine film about a dying hit man traveling across the Argentine outback had a theatrical opening of sorts at MoMA in NYC Tues., Oct. 1, 2013. The NY Times reviewer, Nicolas Rapold, liked it better than I did.
Stories of humanized hit men make for a small but well-trod patch of screenwriting terrain, but “The Dead Man and Being Happy” quickly transcends that territory to become a beguiling road movie
But he acknowledges that at the end "Still, something about the movie falls through the cracks. . ."

The fact is it's a bit of a slog.

P.s.: Alan Berliner's First Cousin Once Removed has the highest critical ratings of any current film presently, Metacritic 96. Oct. 1, 2013.
