Okay. As I recall, from the commentary on The Blues Brothers, Dan Aykroyd's screenplay had to be trimmed down some because he was writing in all the backstory right with the rest. That said, the Blues Brothers is a fantastic movie, probably because of all of that material there.

I just think that it would be better to have all the material there, so that the subtle details get worked out right - knowing why you're going out and killing everything in your path changes things.
