A fine adaptation of Phoebe Gloeckner's autobiographical novel about a sexually precocious 1970s adolescence.

Name : Jesse Hassenger / Alias : AV Club

The Diary of a Teenage Gir is the kind of movie that seems a lot more adventuresome than it is.

Name : Mick LaSalle / Alias : San Francisco Chronicle
It's work, but it's ultimately rewarding work. It tackles some truths that other movies wouldn't touch, not even with a stick and thick gloves.
