Denzel Washington's true portrayal of addiction and alcoholism in "Flight"

Take a look at how Denzel Washington's character, Whip Whitaker creates a disconnect between consciousness and his underlying alcohol and drug addiction. Modern cinema doesn't often put viewers in the shoes of someone who realizes their problem by the end of the film. Some of the saddest scenes in the film occur when Whip is drinking. Additionally, he is a great pilot and his drunkenness does not seem to get in the way of that. Perhaps it would be interesting to see how addiction becomes reliance in this case, and how well the movie portrays two characters: drunk Whip and sober Whip.
