Okay, sure, maybe that behavior is unnecessary. It would be nice to minimize that. Although it’s sometimes hard to notice when an argument has effectively looped itself.
But you have to admit that when editing the final movie in a trilogy you can’t just act like the previous two don’t exist in the thread. There has to be a discussion somewhere about how the previous two films can possibly be adjusted so that you can make or not make certain changes to this edit in an intelligent way.
