The high school musical/comedy “Glee” — which had a one-episode run after the “American Idol” finale to build buzz for its addition to Fox’s fall lineup — is back with another one-minute promo, and dammit if I don’t already really, really enjoy this show. Jane Lynch kills with every line, the writing is funny without losing sight of the story, and I don’t even hate the show-choir singing and dancing element of it. There, I said it. I enjoy this brand of televised musical theater, and I’m not ashamed to say it. Jazz hands just aren’t as cheesy when they’re coming from a kid in a wheelchair.
