It's ok for fans of apocalyptic settings. I would recommend the infinitely superior The Road however. That can be enjoyed as amazing cinema irrespective of genera alignment.
Which is wrong, ptxeixeira... "hell" means "bright".
Saw this at Fantasporto tonight, great ambience, a little Fallout-esque, involving plot and characters. Helped a little that the director was there and told the audience that Hell can be translated in German as "flash of light".
