One Hour Photo is a must-see movie. Robin Williams does an incredible job playing a lonely and creepy man. Unlike most of the pictures I've seen recently (Signs and Minority Report for example), the ending was not flat or anti-climactic. I never once felt like a line was out of place or unimportant. Everything made sense and there were no true surprises. A well-written screenplay and many great performances made this a movie worth seeing over and over.
