Flickchart is simple. And so very addictive.

Here’s the concept. You are presented with two movies at random, and you are then forced to decide which movie you prefer, no skipping allowed. If you haven’t seen one, or both, of the films, you can skip the film you haven’t seen and update the pairing. Flickchart then updates your list of favorites based upon your choices. Eventually, you’ll begin to build a massive and ranked list of movies you have seen.

If you happen to be presented with a tough matchup, Flickchart provides a forum for discussion on what made you decide between the two movies. Is Back to the Future better than Ghostbusters? Obviously it is, but here on Flickchart you get to argue and discuss why you think this is so.

My favorite feature, and the one I find most useful, is the “Movies I Haven’t Seen” list in my profile, populated by the movies I told Flickchart I haven’t seen. If I’m ever looking for new cinematic genius, I can just visit this list which is already sorted by the movies’ overall Flickchart rankings.

However, there are a few shortcomings I immediately noticed after signing up. First of all, starting out is a difficult task. I recommend searching for your favorite movies first, in your order of preference, before you ever begin ranking, and then manually adding those films to your personal Flickchart. Otherwise, the first random movies you rank against each other will covet the top spots immediately (The Devil Wears Prada is not actually my 6th favorite movie, it’s more like my 13th). But the biggest downfall I have found is that Flickchart only adjusts the rankings for one movie at a time. Say you rank A better than B. Then rank B better than C. B moves up in the ranking above C, but A remains in its original position. You’ll have to rank A against B again just to reposition the movies accurately, which becomes pretty frustrating.

Besides its simplicity, Flickchart also introduces the concept of gameplay into the experience, which is one of the reasons it can be so addicting. Deciding between two movies, which may not even be comparable, can be a very difficult task. The quicker you decide, the quicker you get your next matchup. It’s also very interesting just to see which two movies they pair up next to each other. Deciding between a classic Disney movie and Pulp Fiction isn’t something you’re asked to do everyday.

Although Flickchart is currently in beta (with a public launch scheduled for September 9), I can see a lot of integrations and widgets coming in the future, much like those from my favorite music site Last.fm. I read one interview with Flickchart co-founder Nathan Chase who explained that there are already plans to expand the Flickchart format, from exclusively movies, to music, television, and video games, which may or may not have an adverse effect on the site by taking away some of its appeal among movie buffs and cinephiles. But as long as they keep their Fight Club rules (only two guys to a fight, one fight at a time, and fights will go on as long as they have to), I can see Flickchart becoming the source for debating, searching and ranking the best films of all time.
