So frustrating! Just communicate!
If the characters in this film just freaking communicated with each other like normal human beings this movie would be over by the midpoint - well before Manny gets the envelope.
But noooooo! The characters have to be vague and terrible explainers.
Seriously, just tell Manny "Yo, dude that package is money to import a girls son into the country and a corrupt cop is trying to steal it. Can we maybe stop and talk about this?"
Done. Movie over.
I mean I understand that they don't do this so that the movie isn't 40 minutes long. But a good film doesn't have to rely on implausibility to make it work.
