So if my previous blog entry caused you periods of severe angst as you tried valiantly to reconcile your inner Neil Sedaka with your outer Kurt Cobain, I apologise. Me bad. Never again will I so flippantly herald a theory like popstrology as the answer to all your problems.

This time I really do have something that will make your life a little easier. Ladies and gentlemen, get ready for whattorent.com.

For many people, going to the video store and trying to find a movie to rent is a disillusioning experience. You like to think that you're easy to please. Not so picky. A movie lover. Then you walk into your local video store, find yourself faced with hundreds of movie titles and after 10 minutes your hands are forming little fists, your jaw is clenched and you're muttering to yourself that you knew you should have stayed home and shampooed the dog.

Twenty minutes passes. Still no movie has been chosen. Every movie title you pick up seems to feature Martin Lawrence dressed as a woman. Or people being disembowelled by a serial killer with a limp and a crazy Russian accent. Your girlfriend is carrying around Hope Floats because "Harry Connick Jr is hot." And no one will listen to you, mainly because you've burnt them before. (Last month you convinced them to rent Gigli.) It's no wonder that a trip to the video store holds as much appeal as a visit to the pathologist.

But there's good news! Those days of bad movie rentals are behind you thanks to whattorent.com - a website that provides suggestions based on your personality and your mood. That's right. It's like RSVP for movie lovers. (If you don't know what RSVP is, consider yourself lucky and just move on.) When you log on to whattorent.com, it asks you to take a quick personality test.

There you'll be faced with 20 questions asking you to describe everything from your first love to how you like to order food in a restaurant. The questions seem obscure and inane (like the one asking how much money it would take for you to wear a bright green bum bag around for the rest of your life), but these questions have been formulated to decipher your true personality. Another two questions ask about your current mood and then voilą! The website starts recommending movies that it believes you would love.

Take it from me, it's eerily accurate. The first movie it recommended was actually one of my favourites: Before Sunrise. Close friends had similar experiences.

So how does it work? The site was designed by Americans Matthew Kuhlke and Adam Geitgey who based it on the relatively unknown LaBarrie Theory, which states that "movie viewers emotionally interact with a film in the same manner that they interact with other human beings."

"We decipher your personality and calculate how you would respond to each movie in our database," says Kuhlke. "Each movie in our database is evaluated and analysed as if it were an actual person. After we learn what type of mood you are in we perform a few algorithms with your personality model, mood and the movies in our database. These operations give us an idea of what you would experience if you watched each movie in your current mood. We use your feedback to modify our algorithm to perfection. We have recommended over 350,000 movies and satisfied about 78 per cent of our users."

Kuhlke says the site's success stems from the fact it won't stereotype you into a certain type of taste. He says other "recommendation engines" on the Internet (like those on Amazon.com), reply on your past movie choices to predict others you may also enjoy. "We recommend movies based on who you are and what mood you are in. The fact that you normally enjoy incredibly depressing movies shouldn't preclude you from a quality romantic comedy once in a while," he says.
