Good acting! Some memorable characters and scenes, esp John's AA sponsor!
Yet, at times, this film had poorly-done, confusing scenes and the film had a feel of low-budget and quality, esp the first half of the film!
This movie was based on the real person, John Callahan, and his biographical story!
I hope it will be remade with a larger budget and a better-written script, more complete of who John really was! Perhaps, it ought to be a series! There was much more to this man from what I have read on the Internet!
