First off, you need to understand that this is an ultra low budget movie that feels like it was shot on an iPhone and a gimble. There are some plotline issues and there and some serious issues with the acting.
Now, the movie is entertaining and better than many of the low budget movies I have watched. So much of it seems far fetched, but that is the point of a movie right? Something that is entertaining, and you can just sit and watch without having to second guess everything. If you get the opportunity, watch it.
Lastly, the idea that you could take a city in New York because guns are illegal... That has so many holes.. LOL
