Well it's understandable, not everyone is a Buffy fan...hell, even I wasn't for the longest time and I still haven't gotten around to actually watching it straight through. Watched Angel though (it was the only thing on at 6 AM before I went out to school). But yeah, Whedon is a beast, and definitely takes things like fan input to heart. He's the king of one liners as well.
Command Board, pretty much just makes it so you can gather more commands and level them up quicker. You can pay attention if you want, it's pretty optional. If you're playing Proud Mode, you might want to look into it more just to make life a bit easier for you. Also, make sure you get every single Xehanort report. That means taking a visit to the Mirage Arena with Terra.
