I finally broke down and gave this show a watch after all the great reviews and it's an enjoyable show. It's a musical with a huge ensemble cast that takes place in High School (however, it not like the high school High School Musical films.
The shows deals with some very un-family friendly issues such as teen pregnancy, homosexuality & infidelity, isolation & depression. The show does have its flaws though, it tends to box some characters into stereotypes but I'm guessing thats just the first season start off & they'll give some more depth to the characters and make them more than cardboard cutouts.
Actually, they specifically boxed people in on purpose. Or at least I'm pretty certain that's what I read. So while that might look like a downfall, it is done on purpose to make jabs at people.
