Summer Heights High (HBO)

Shot at an actual Aussie high school, the series' unconventional-but-clever mix of actors and real school students and staffers makes it both funny and genuine. In fact, all three of Lilley's performances are so convincing that it's sometimes hard to forget that they're not real. But as funny as it is, the show also taps into some very serious issues about Australian public school, including teachers' inability to cope with difficult behavioral issues, racial prejudice, class distinctions, and the quality of education offered at public vs. private schools.

While Summer Heights High offers plenty of hilarious moments, it also has some poignant scenes, especially when teachers express true concern over their students and when prejudice leads to some unfortunate misunderstandings. And the whole package comes wrapped in some very mature content, including constant strong language, racial slurs, and homophobic references (all used to make a point, but still). While they're not treated as positive things, references to drug use and some disturbing sexual behavior are also major themes of the series. In short, it's not meant for kids -- but for mature teens and adults, it's definitely quality entertainment from Down Under.
