Aja is a pretty cool dude, and if the project wasn't already in Fincher's hands, I would be cheering for Aja to pick that bad boy project up and make it immediately. However, Ficher, in all honesty, is 10x the filmmaker Aja is. Maybe thats becuase I'm a MASSIVE Fincher fan, but that's the way I feel. Either way, done by Fincher or Aja, it would still be a treat to see.
