Let's get physiological. A thesis-heavy experiment about the nature of love, Dopamine (named for the amphetamine our bodies release during arousal) centers on a cynical software designer played by John Livingston. He's hot for teacher Sabrina Lloyd, but Livingston, we presume, views every emotion through a microscope and regards attraction as purely chemical responses.
So, despite their growing connection, the two have to overcome philosophical differences--and address past wounds--to make their relationship work. Dopamine was developed, appropriately enough, at the Sundance Filmmakers Labs, and its characters and situations feel less organic and more designed to elicit certain audience responses. Fortunately, there's some chemistry between the appealing leads, and the acting is solid throughout. At the very least, maybe seeing this film could count for extra credit in high-school biology.
