Rand, Winston, and Johnson have a small tech startup company in the Bay Area that's developing a artificially-lived computer character, Koy Koy the bird, who can hear and see and interact with the user. Koy Koy gets placed in a kids schoolroom for testing, and Rand develops a relationship with one of the teachers, Sarah. Rand learns that his scientific understanding of human mating isn't necessarily a roadmap for the real thing. Written by Martin Lewison <dr@martinlewison.com>

Rand: My question is, does the chemical make-up between two human mammals make up our personal involvement a moot point?
Sarah McCaulley: Of course, it's all chemical to start with. It's all just signals to communicate with these bodies we live in, but true love is incredible, all consuming.
Rand: No I totally agree with you, all consuming. BUt so is the lust, I mean is it possibly rooted in physiology rather then

Really Enjoyed It
20 October 2003 | by hprevan2See all my reviews

It's a wonderful movie. The premise is clever. All of the acting is well done. The character, Sarah (Sabrina Lloyd) really caries this movie, as Rand (John Livingston) is a likable underdog type that you instantly root for, but Sarah, while likable, has a darker side and if the audience doesn't care about her then the movie falls apart. A less charismatic and talented actress could not have pulled this part off, but Sabrina Lloyd seems to handle it with a natural charm that makes it look easy. I have no doubt that she will have many opportunities thrown her way based upon her work here.

This is a great movie, however a few minor details could have made it better. At just over 80 minutes, they really could have filled out the movie a little more. I can't help but feel that there is a lot of story left untold and some of the scenes feel a little disjointed. With it being an independent feature, I'm sure a lot of this has to do with budget and time (trying to get into Sundance.) I also would have enjoyed a few more light moments between characters.

I think one of the reasons some people haven't taken to it is the mistaken idea that it is a romantic comedy. It really isn't. There are a few light moments (don't know if I would even call them comedic moments), but this is definitely a drama. The issues and material are serious, so anyone waiting for Sandra Bullock type goofiness, Meg Ryan over sentiment or Three's Company sexual innuendo miscommunication are going to be disappointed.
