In the NFL, every practice could make or break you. If you dropped one ball, you'd worry about getting cut.
Editing yourself is like an irksome coin toss. You've got to strip yourself of super ego and operate from the id. Maybe I've got my Freud mixed up. It's just hard to trade a beauty shot for the performance with truth and a brightly lit zit.
But what's interesting is now - and not only in horror, but across the board - the studios basically only make B pictures with A budgets. That's the biggest difference.
