I don't want to overdo it, but here's another review of the film from Film Threat which is an unusually honest magazine. I'll just leave you with what I think is the really important part.
“24 Hours on Craigslist” is the ultimate people zoo. This isn’t bullshit reality television fodder where the beautiful people go to grab their fifteen minutes and hopefully a whole lot more. No, these are regular people, genuine in their strange habits and they have no problem sharing their eccentricities with the world. So where does one go to find all of these bizarre folks? Filmmaker Michael Ferris Gibson didn’t have to look much further than Criagslist.org.
