Can you review a movie in 140 characters? TwitCritics thinks you can. This site assembles tweets about current releases and distills them into a rating. You can follow them by RSS feed, on Facebook, or, of course, on Twitter. The reviews so far seem to skew more positive than other aggregators like Rotten Tomatoes, probably because tweeters are more motivated to post when they are feeling enthusiastic. Civilian reviews in general tend to be more positive because people only buy tickets to movies they want to see so there is a selection bias. It is fun to see how the fans react, just another way Twitter is becoming the go-to real-time temperature-taker for the hive mind.
Thanks to my beloved nephew Dante for this suggestion!
