An excuse to animate violence.
Theres a lot of movies that are just a bunch of guys just shootin' each other up for no aparent mind-numbing reason, however it takes some thinking and planing to make one that is wild enough to be enjoyable, or even funny enough to be enjoyable. Like maybe an office intern who has had it and (after showing their boss yell at them) beats the crap outta his boss. However this is one of those "just a bunch of guys shootin' each other up for no aparent mind-numbing reason".
