Very interesting, thanks for the writeup.
On a related note, I'm curious how many here find user ratings of new movies coincide with their own. Personally, I've been sticking to critic reviews because the authors usually have a much larger base for comparison and developed tastes than the casual movie goer like me, and because user-submitted ratings like IMDb can be highly inflated as waves of unusually high ratings pour in in the first few weeks of the release ("Best romantic comedy EVR, 10/10!"). Once the dust settles, the reviews tend to sober up a bit and even out at a value that I tend to agree with more.
