Where to begin? It seems to be written by smart-assed male high school students with all sorts of authority problems. Since when is simulated male to male anal sex funny? Sexual humor is such a cop-out. There is so much going on in the public schools to parody and pillory, a truly talented writer wouldn't have to resort to adolescent sexual humor.
I've given it a "3" rather than an "awful" only because there is only one character that comes anywhere near funny and that is the school principal. I'm a former teacher and I recognize that character! He's a composite of the worst of public school administrators! The only way a person can rise above classroom teacher in the public schools is by being a major wimp, to bend to whatever politically correct wind happens to be blowing, no matter the source.
Now, build a comedy around THAT character and cut out all the adolescent male sexual humor and you'd have a great show!
