What I really, really liked was, that for once on a TV Show it wasn't the Dad being against gays and being super "religious" but the Mom. Usually, Moms are portrayed as the more open-minded ones, but here its the other way around: Really liked that twist.
Well most of the time the Dad is the one shown as being closed minded when it's a gay son and it's been my experience that even guys who think of themselves as "liberal" and not at all homophobic have trouble accepting that their son is gay. They seem to think you're not a "real man" if you're gay and that they did something to make their son that way, that they weren't a good example or such BS.
