Wow, you guys are real hard on Bakula, poor guy
I loved Enterprise personally.
But DS9? That's what really hooked me into Star Trek universe completely. Sure, TNG was great, but DS9 sold me. Absolutely loved it.
As for the topic, I think Brooks is definitely an odd guy in real life and his acting is certainly unconventional when compared to the other captains. However, as noted above, I think this just makes him a more interesting person to watch. I certainly had a similar impression when watching him that there was always something beneath the surface for his character, waiting for it to erupt at any moment. A controlled crazy.
