From a technical viewpoint, very well executed - lighting and Cinematography were excellent. As for writing - every character in this is so well conveyed that the actors are able to do the story justice. Joaquin Phoenix did an excellent job as expected - both him and Jonah Hill really showed some emotional range in their roles. Rooney Mara's performance was great and her chemistry with Mr. Callahan was palpable; although not nearly as much so as Mr. Callahan's screen chemistry with Donny. Even the time Jack Black and Joaquin have on screen together is magical - and weirdly enough I don't think they could've cast anyone better for Jack Black's character.

The movie ended up being more of an exploration of 12 step program than I expected, but by the end it actually gave me deeper insight and understanding of those struggling with alcoholism who seek help. Knowing tons of people who've gone through the program (recurring ones and success stories) it's given me a slightly deeper appreciation for anyone's struggle/experience.
