Ended in the same place it started, if a third film is made future generations can probably watch the first and third without needing to watch this one.
Nothing is really achieved. The musical aspect doesn't really help.
Casting for early quin wasn't too good.
Joaquin Phoenix had a great peformance.
The locations where good and the prison was pretty sick, however I think more could have been done in a 2 hr film beside singing and court rooms.
