Haha, oh wow. It's weird. We had almost a solid three weeks of only top fifties movies (to which there appeared to be no end), then these last few days we have really low scoring movies.
I suppose the system evens itself.
Kind of a good thing really. It's overwhelming when every movie on the front page has a 4.24+ (and you feel like score is no longer a good indicator of quality), and it's intimidating to new authors (as I've heard a good number of them complaining about there being no room in the game for new players these days).
