Avery Brooks is a fantastic actor. People have problems with his voice and his heavy breathing, but that's how he speaks in real life as well.
Also when they consider his "It's real" meltdown to be overacted. No meltdown can EVER be overacted. I've witnessed two. Seriously, there is no such thing as overacting a serious meltdown. Brooks did it wonderfully.
Sometimes I think Brent Spiner, Leonard Nimoy, Robert Picardo and Jeri Ryan headed into the wrong direction with their characters (especially Picardo as the EMH), but that doesn't mean they acted badly. But sometimes it appeared they forgot about the logical and even artificial nature of their characters.
