As it stumbles to the finish line, "Zipper" means to be a condemnation of our political system, but the impact is negligible. The fate of a dull enigma doesn't have much weight.

The film as a whole feels sort of retro as a tawdry cautionary tale.

Lurid and cheesy and sometimes unintentionally funny.

It's well-acted, dramatic, has several thematic elements that are solid, even if it doesn't always peel back the curtains to reveal the reasons why or make use of the consequences of the protagonist's choices.
