Being a fan of both Christopher Nolan's earlier and later works I had high hopes for Insomnia. It starts out as a normal cop/crime movie, but soon turns into an psychological thriller. The story itself is not that original but is still interesting to follow. My interpretation of the movies theme is that we are never only good or bad, but shades of gray.
My first reaction after finishing Insomnia was that there was something missing, after a while I realized that nothing was missing it was just me that had to high expectations. Insomnia is not a bad movie in any way, but it is not a masterpiece ether. It is what I would call a well crafted, well acted but overall average thriller.
Al Pacino is the star here. His transformation from start to finish is amazing and once again he proves that he is a brilliant actor. It was also nice to see Robin Williams in a more serious role. The rest of the cast could however been better. Overall Insomnia is a decent thriller, it keeps the viewer interested all the way to the end, but it will probably disappear from your memory a week later. 7/10
