I watched this a while back, and thought an actual fist fight was going to commence between Gates and Marina. In fact, I had some respect for Marina until I saw this. She just comes off as very unprofessional. And while she may have had a point about young actors, the way she acted toward Gates when she spoke her piece seemed rather juvenile. There had also been a panel that was just her and Michael Dorn,and I thought that she was acting that way because they're good friends, and were just having fun. From what I have read since, it sounds like this is just her, the acting like a drunk loud mouth routine.
But the rest of the panel was really good, I thought.
