Absolutely amazing. Not my usual genre of "go-to" movies, but this far outseeded my expectations. Incredible performances by both Joaquin Phoenix and Jonah Hill. Even some great scenes with Jack Black.
If you or someone you love is currently or has struggled with addiction, this movie should be highly relatable and also extremely real.
I really would recommend it (although maybe not when you're in the mood for a "feel-good" movie haha). It is a "must-see" in my books.
