I saw this one when first broadcast in the US, then saw the remake with Michael Douglas, then watched the original again last night. I was amazed by the degree to which the quality of the original exceeded that of the remake, with the possibly sole exception of Benicio Del Toro's performance as the Mexican police officer.
In every category, acting, writing, photography, music, editing, the original is superior. It managed to project the same message without being preachy, and the characters had much more depth and scope.
One other observation: when the remake came out, much fanfare and praise was directed at Soderbergh for "his" concept of filming the different locations with different color pallettes: Mexico was yellow, Washington blue. This is a concept he lifted whole cloth from the director of the original, which I had not noticed the first time I saw it, but did notice the second. Pakistan is filmed in ocher hues, Hamburg and London in shades of blue and grey.
When the Hollywood product came out, I felt like I was the only one on earth who had seen "Traffik" the first time around. I sincerely hope that the movie will spark the interest of others to watch the mini-series--it's worth the investment of time, and a great education, not only on the drug and social issues, but on how quality gets diluted to appeal to the lowest common denominator.
