I didn't know before seeing this film that undocumented migrants could work, have businesses or jobs in the US but not be allowed ever to return if they leave even for a short holiday. This film is a cri de coeur to change this iniquitous system.
The actors were simply perfect, both the young incarnations and the older ones. It was easy to imagine that these two sets of main characters especially could have been the same people in their earlier or later lives. I especially liked the touch at the end when we see photos of all of the real characters at various times in their lives culminating in a photo of the real guys who inspired the story posing with the actors who played them.
One other refreshing thing was the absence of simulated sex going on. Gay or straight, it seems to be obligatory nowadays in films and TV that people have to get into bed and show it all after the merest kiss.
As this was based on a true story, at some points the tension flagged; we knew they got to the States, for example. However, it was still a revelation to see the horror of getting over the border and how easy it is to die on the way.
At an hour and fifty one minutes, this was just right in length. There wasn't any padding at all. It was a fascinating glimpse into attitudes and adventures that most of us never see. Bittersweet at the end but life went on. I do recommend this film.
