Excellent dark comedy!
For people who like dark comedies (me!), this one is a success. Just when you think it can't get worse...well, you know. Every possible wrong decision to be made is made, every action is screwed up by incompetence. The moral of the story? Do the right thing to begin with; it'll save you a lot of trouble later on.
The end is a bit disturbing, but that's the moral of the story. This is truly about good people doing very bad things.
