High School Record was an high school mockumentary. However, while it was experimental and set in a high school, it did not annoy me like last year's Chaza Show Choir.
There were quite a few parts that did make me squirm, but I was squirming with recognition. They were "I've been there! I've seen that!" moments. Most of the cast are not actors but young musicians in punk bands. Occasionally the lack of polish hurt the scenes, but usually it made it all feel fresh and genuine.
The parts that I really could have done without were the drama class/drama teacher scenes. Her character was pretty one-note and over-the-top, and it tended to detract from the rest of the atmosphere.
Overall, it made me nostalgic for my geeky high school days, while at the same time keeping me extremely grateful that I will never have to do them over again.
