This movie is entirely sincere. From the very first words you see on the screen, before an image is even placed, you feel drawn. The writing, cinematography, acting, music choice, EVERYTHING has been perfectly orchestrated and placed. I can see this film not going very far if put into the category of "romantic comedy" most people have become accustomed to. But, 500 Days of Summer stands in making love pure in its intent. This is the kind of film you admire for carrying out the thoughts you think daily- however random or bizarre or obscene; it's acceptable and it's natural. Just GO SEE THIS. :)
