I would tend to agree with creamygreen on the predictability and stock archetypes used to fulfill the writers premise. But the more interesting thing about this film is the premise itself. Can love be boiled down to just science? Can the build up of dopamine make me want to cuddle? Science is always struggling against the nature of human beings with such things as religion and human emotion. Such intangibles make the separation between what you feel and what you can prove the cornerstone of any good debate. The premise for this movie was a good one, it's the execution in the writing and scene development that fell apart. I would love to see the writer do something different with this premise and see whether or not it will draw all of us in. After all aren't we all familiar with something we just "know" but can't prove?
