I agree with 005, 4 balls makes more sense (because it doesn't), 4 balls is way funnier and it is true to the source of the ball rating system established my sallyliao in 2011 (the Sallyliao Ball Rating System).

Nice! Loved it. The Mist. I was pleasantly surprised, despite some dodgy CG. Really loved the ending. 3 balls out of 4 balls.
And when someone messes it up, we can quote Picard at them... :D
