I Kinda liked the eyes cuz in the books they are described as having silver eyes. (plus it made Jenna Berman look hotter then she already is)
My only qualm was the hair color and choice of spartans, I love Kelly and who they picked for her, i just would have rather seen Linda with her red hair.
And also i did a little digging, when i said earlier i would have preferred Sam, It would appear he's already dead when this battle occurs.
