I'll be honest that I don't know what it's like to be addicted to drugs or alcohol, and can't speak to the accuracy of the film in that regard. So I am reviewing the story on things such as artistic feel, acting, plot progression, etc. I did really enjoy this movie, which is surprising considering its content. The characters and their struggles felt real, and the movie had enough balance in the drama to not drag you down too low.
I felt that the artistic elements were beautiful and made sense to the plot. The characters seemed reasonably well acted. I admit I may be biased though as a "Two Broke Girls" fan. I actually thought a lot of the supporting cast were really good too though, and weirdly the person driving the rickshaw seems like their character's story should have been in there a bit more, as it was hinted how important they were to Renee's character, but not as well covered. I did think the person who's place she stayed at seemed a bit more shallow than their character should have been, and am uncertain if that was writing or acting.
Some people have considered this as an anti drug propaganda film, and maybe it is, I can't say. It's based on a true story, and as all films based on true stories we will never have the whole story, not just because the 2 hour time limit, but because there will always be more to the story to the people who actually lived it.
