Firstly to the writers: as a British guy, the title means absolutely nothing to me! 4.0 sounds rather low.
This isn't one of the best in the series by any means, but it still has many good points. It starts out looking like the usual pushy mother syndrome forcing an over-achieving kid into a breakdown, but the reality is thankfully quite different, if not exactly a huge surprise.
I must admit I was pleased that the ending was positive. I know it doesn't always work out that way, but there are enough downer endings! Great choice of music too with Joni Mitchell's plaintive voice over the final scenes.
Reasonable story, but not a classic.
