Benjamin Sisko alias Avery Brooks actor. i am watching ds9 again, and i still think that Avery Brooks acting is wooden even after all this time my opinion hasn't changed. he was definitely not the right person for that role. and that has nothing to do, with black and white. before you say, is it cause hees black
Possibly.
But there are a couple of things to consider before passing total judgment.
He is coming back to his first "real" command position since his wife was killed.
There would be various levels on which this could effect him.
Does it remind him of when he was on the shop where his wife was killed by being a command position? Or just being back out in space? Out in space now is he worried about his son? All of these to some degree?
Also(Starfleet isn't a military, yea, okay) since he has risen to the level of commander, he has a certain level of professional bearing that he has and must maintain.
In perilous situations you can't be the person in charge breaking down in tears, running around throwing things, screaming at people, whining etc. ( that's one of the reasons I hate Kira in the first couple of seasons)
In my military experiences the higher ups were very controlled and calm even in bad situations. If they hadn't been, I'd have had no confidence in them. I would have not wanted to follow them in to bad situations.
He may have not been the greatest actor but when you factor in, the Character he was supposed to "be" you might see him differently.
