I gave it a go. Rated about 130 films in less than half an hour.
Most of the predicted ratings seemed accurate, generally within a half a point. Though there were a few amusing exceptions, like Star Trek V, which it predicted I'd give a 3, when I gave it a 1, if that.
Dunno. In the recommended list, I didn't see anything I hadn't yet rated, but really liked. Heck, in the recommended list, I hardly saw anything I previously saw, which was suprising.
It was also recommending a bunch of old movies to me too, like stuff from the 1940's and 50's. I do appreciate movies that actually have a coherent plot, but the old stuff doesn't seem to grab my attention, at least when I'm at the video store.
Okay, that's officially the coolest thing ever. It's actually inspiring us to sign up with Netflix again, because there's a lot we want to see, and even more that we want to re-watch.
I find it harder and harder to determine whether I agree with the predicted ratings, though. It's hard to second guess the website. :-)
