|Apparently there are seven teachers.|
I'm sure that the show has some perfectly good advisers who help the construct some form of narrative skeleton. The school looks like a school, and the kids look like kids, albeit with the usual Dawson casting. But even in the most outlandish of escapism, the science can be as bollocks as it needs to be- it's the human dimension that has to ring true, otherwise you're no longer watching a human narrative, but the irrelevant actions of toy soldiers. Exhibit A-Z: WR.
It's depraved- last time I looked, the asisstant head was gaily sleeping with a GCSE student (the Head's daughter, no less, which probably gets him some special level of Dante's Hell), and inexplicably NOT being clapped in chains like les oubliés. The Spanish teacher did pounce on some A-level giant, but that was OK, apparently because it was a pretty, female teacher nailing a young man, so no child protection issues there, no-siree. Then there was the unlovely scowling harridan in year ten who accused the dinner lady's son of rape. Cue: police, etc. But at the end of the episode she broke down and admitted it were all a laugh, and like an episode of I love Lucy, everyone hugged it out at the end and agreed to say no more.
