fleshing out Bana's character is the point of the Countdown prequel comic miniseries
hey, if Cloverfield fans are allowed to reference the ARG, I can bring up the prequel comic

I thought he was an okay protagonist, even so. Trek villains can be divided into two groups: Khan, and everyone else whose names you can't remember
EDIT:
Star Trek, though, has never been about antagonists. It's about working together as a species (and with other species) to overcome our shortcomings and accomplish great things. It's man vs. himself, and man vs. nature, not man vs. man. "Better antagonist" isn't really where Trek should be going
