First, let me say that Sisko as played by Brooks is an infinitely more interesting character than Archer as played by the miscast Scott Bakula (a good actor stymied by his miscasting). But Brooks is so odd as Sisko. I am rewatching the series (as a non-fan who wants to give the series another chance), and am at early season 3. Brooks is usually either fulminatingly angry or weirdly, almost hysterically enthusiastic. In the Dax episode "Equilibrium," however, Brooks looks and sounds, frankly, bored. I have heard Brooks speak scoffingly about Star Trek, and dont know if these attitudes affected his performance. I dont know if people feel that his performance improved over time. But while he is undeniably a strong presence, Brooks is also a maddeningly erratic and uneven one.
