My Fair-Weather Friends Cop Out short

This is an idea I've had for a few months now, originally it started as a documentary about the homeless, before becoming a series of mockumentary styled vignettes, and it eventually turned into this. I wouldn't call myself a professional, I'm just a film student with the urge to write.

So yeah, I was just wondering if it all made sense to people, if the characters were interesting and if it was generally not terrible. Yeah, just tell me what you think + how you'd fix any of the stuff you weren't too fond of. Feel free to throw in anything that comes to mind!
