Lost potential

Good movie but I could not help but to feel that they skipped some scenes that could've been a real treat.
And I'm obviously talking about the meetings.
It seems that they focused a bit too much on the anger and them flying of the handle and trying to control it.
And that was great but the actual topics were just as intriguing if not even more.

Because they were smart, funny, a bit dark and they just felt real.
How they talked about prison, puss etc.
I wish they showed more of that.
