Aimee Teegarden
She's hot but she's like 24, not 16. You see her jogging at the beginning of the episode and you're like damn she is a beautiful woman not a teen. Then they try and pass her off as a 16 year old in high school. That isn't even remotely believable.
Why can't they hire real teenagers for TV? I get that they prefer actors that are 18 and older for lots of different reasons, but still. They should hire actors in the 16-19 range if they want their characters to look like real teens.
