I think Nolan (Nathan Fillion) is attractive, not HOT, but attractive. He's also my age (IRL). I think Jenna looks younger than her age, but IMO, I think the issue is she's just not right for the role. I'm not buying her as a female firefighter and I agree that she has no chemistry with Nolan. However this is TV, and the male star of the shows always have a super good looking, thin girlfriend/wife no matter how ugly, fat or dorky they are.
