Uhura wasn't that light
Zoe Saldana as Uhura? Come the fuck on?!
Did they pick Zoe simply because she's happens to be African-American and is semi-known? Ok, she is beautiful, but she doesn't seem to have enough charisma. In most of her roles, she comes off as kinda bland.
Sylar at least has some some personality, a bit of depth, so Zachary Quinto as Spock sorta makes sense.
After the travesty of 'Nemesis', JJ Abrams is gonna have tons of doubt and nay-saying from the audience. My advice (not that he's asking) is to tread lightly with casting. I guess the producers think all the "Lost" fans will see the Trek movie, simply because he's directing. I think not, it will be the die-hard Trekkies and sci-fi fans, if they're lucky.
