My first review on imdb. Why for this particular movie? Because after watching it with my nephew, who is disabled, like myself, we were both very disappointed and a tad offended.
When the main protagonist meets Drake, the movie is fun and wild. Drugs, guns, girls.
We get some flashbacks that are a part of the final "twist", which is some psychological BS. Which is fine, except whoever wrote this probably never heard of muscular atrophy.
Even this aside, the ending is kinda selfish on the part of the main character.
8 for the first part and Drake, whose story and motives were better suited as the base of the movie.
3 for the ending and surprise revelation.
