This is a good example of how someone can take a tiny budget, a fun idea, a skeletal story and a cast/crew of unknowns and whip together something fun and exciting. It's better than a lot of other action movies out there (although there are no typical ugly special affects, e.g., pyrotechnics, bullets bursting through bodies, etc.) The banter between the protagonists is a mixture of Quentin Tarrentino meets caffienated salesmen.
I don't know any of the cast, but most of them have lots of charisma.
Some may grouse that this movie was too self-conciously indie, too derivative of Resevoir Dogs or is just an ambitious person's calling card - but in my mind, it puts a lot of big movies to shame. It's certainly better than anything that goes direct to video.
If you wanted to improve this movie (remember, we're dealing with newbies here), the FBI personnel were used to tell the story. Their role as the storytellers was a little wooden, too obvious and not all that necessary - so I would trim their parts down.
