I am very excited. I was reluctant at best about the last one as that's MY Trek you're messing with (Movie!Original Crew.) But about the time Bruce Greenwood showed up I was starting to think okay, this might not be so bad, and then as they arrived at the Enterprise I was basically "Okay, J.J. Abrams is my master now."
Best/saddest is Karl Urban as McCoy. Reportedly Leondard Nimoy teared up the first time he heard him in-character on the set as it was so much like DeForest Kelly.
Not a trekki myself, but Benedict Cumberbatch??? Sign me up! I know he isn't traditionally handsome, but there's something about him... makes me want to flip my mane around like a horse in a calendar. Hehe.
