Perhaps the Wagner clan found making it cathartic, but for the viewer it is merely punishment.
Not rising to the truly repulsive, the infantile self-absorption of the cast would drive most any non-Wagner to claw his or her way out of the speeding van even at the risk of life and limb.
The quirky annoyance factor of the cast (particulary of the straw-chewing patriarch) is not matched by an emotional pay-off. The (spoiler alert! z-z-z-z-z...) reconciliation is utterly toothless. These people SHOULD be separated.
This indie movie is scary in that it shows how little money and little talent are required to get drek produced nowadays.
