World unto itself
AA is a world unto itself. This was realistic, but depressing watching Lewis relapse. But at least he showed back up again.
This doesn't show there are alternatives to AA, and bring out that some people have serious problems with the tenets and methods of AA. I guess that would be hard to address in this type movie, but they could have had one of the members voice some issues that trouble people about AA.
I'd recommend the movie, but not watch it alone. And if you have issues with AA, look at Rational Recovery, SOS sobriety, Lifering websites.
