It's easy to say out of the four seasons "which one was best" or "my favourite season was" but looking at it as a whole, this was a well needed series, showcasing hard hitting issues through the eyes of school children. As a gay man, now 34 years old, I only wish something like this was more accessible or talked about when I was in high school. EVERY single topic throughout the four seasons were done with grace, compassion and honesty. The whole cast and crew should be incredibly proud of what has just ended. Bravo!!
