I meant the alternative of not doing one at all. As opposed to venting, or trying to change things. Even if you try to be positive it is problematic. Firstly if you are so positive, then why are you leaving? Secondly even only being positive means you leave things out. How is someone going to feel when they read it, and see you don't mention them or mention them enough. The good light/positive leaving can be better accomplished by your farewell email, as you get to choose who it goes to (most likely far more people than just the exit interview) and you can put in it whatever you want.
