Has anyone had the misfortune to actually watch the TV show of that ?
Thankfully I haven't
Is it 45 minutes per episode of that screaming and dancing
I've seen every episode so far, and it's obviously going to have singing and dancing in it, as they're a glee club. That's what they do. They've done an assortment of songs from different genres throughout the series. They'll do current popular tunes, to songs from Singing In The Rain. Their Halloween show was totally Rocky Horror.
The second series has been seen as quite controversial in the States due to the subject matter tackled, from drugs, sex, masterbation, lesbianism, homosexual bullying and religion.
It's no where near as bad as folk think.
